Resize for Instagram — FreeJPG, PNG, WebP, AVIF, HEIC — Instagram-ready sizes, aspect ratio lock, batch export.
Resize image for Instagram to the exact pixel dimensions that each format requires. The correct Instagram image size depends on where the photo appears: 1080×1080 for square posts, 1080×1350 for portrait posts, 1080×1920 for stories and reels. Resizing a photo for Instagram to the wrong dimensions causes cropping, letterboxing or blurriness after upload. This tool gives you every Instagram size preset plus custom dimensions — resize your photo for Instagram in your browser, no upload required.
Instagram image sizes — what every format requires and why it matters
Knowing the correct Instagram image size for each format is the starting point for every post. Instagram displays images at different dimensions depending on where they appear — the feed, stories, reels, the profile grid and the post detail view all use different pixel dimensions. Uploading an image at the wrong size causes Instagram to crop it automatically, often cutting off important parts of the frame. Uploading at a size that is too small causes Instagram to upscale the image, producing a blurry result.
The most used Instagram post size is 1080×1350 pixels (4:5 portrait ratio). Portrait posts take up more vertical space in the feed than square or landscape images, making them more visible during scrolling. For creators who want maximum feed presence, portrait is the recommended format. The standard Instagram square size is 1080×1080 pixels (1:1 ratio), which works well for products, graphics and centered subjects. Landscape posts use 1080×566 pixels (1.91:1 ratio) — these occupy the least feed space and generally see lower engagement on mobile.
Instagram Story size is 1080×1920 pixels — a full 9:16 vertical frame. Stories and reels that are not uploaded at this exact ratio get letterboxed (blurred bars top and bottom) or cropped. If your photo does not naturally fill a 9:16 frame, use this tool to add a background fill or crop to the target dimensions before uploading. For profile pictures, upload at a minimum of 320×320 pixels — Instagram displays profile photos at 110×110 px but crops the display to a circle, so center the main subject.
Resizing a photo for Instagram without distortion requires aspect ratio lock — keeping the width-to-height proportion fixed as you scale. Without it, a photo resized to 1080×1350 from a 16:9 landscape original gets stretched vertically, distorting faces and shapes. This tool locks the aspect ratio by default, scaling proportionally and fitting to the target dimensions without stretching.
All resizing runs locally in your browser. Your photos never leave your device — no upload, no server, no third-party access. Resize any number of photos for Instagram in the same session and download them ready to upload. No account, no daily limit, no watermark.
You can also crop images for precise framing, compress images to reduce file size after resizing, or remove backgrounds before resizing for Instagram.
- 1Upload your photo
Drag and drop a JPG, PNG, WebP, AVIF or HEIC file onto the upload area, or click to browse. All processing runs locally in your browser — your photo is never uploaded to any server.
- 2Select an Instagram size preset
Choose from the Instagram format presets: square post (1080×1080), portrait post (1080×1350), landscape post (1080×566), story or reels (1080×1920), or profile picture (320×320). Or enter custom pixel dimensions for a specific requirement.
- 3Resize and download
Click "Resize" to process the image. The output matches the exact Instagram pixel dimensions with aspect ratio preserved — no distortion, no unintended cropping. Download the resized file as JPG or PNG.
- 4Upload to Instagram
The resized image is ready to upload directly to Instagram. For best results with Instagram's recompression algorithm, use JPG output at quality 80. Pre-resizing to the exact Instagram dimensions prevents Instagram from applying its own resampling, preserving sharpness.
Who resizes images for Instagram — and what they need
Content creators — resize photos to fill the feed without cropping
The difference between a photo that fills the Instagram feed and one that gets letterboxed or cropped is the aspect ratio. Resizing a photo for Instagram to 1080×1350 before uploading ensures it takes up the full portrait frame — no wasted space, no unexpected crops. Creators who batch-shoot in landscape or square format can resize all their photos to 4:5 in a single session before scheduling posts.
Brands — consistent image dimensions across all social posts
Brand accounts need consistent visual presentation. Uploading images at inconsistent Instagram image sizes results in a grid that looks mismatched — some posts square, some portrait, some letterboxed. Resizing all images to a single consistent format (typically 1080×1080 square for product grids) before uploading creates a uniform, professional-looking profile.
Photographers — resize shots for stories and reels without blurry letterboxing
Photographers often shoot in landscape (3:2 or 16:9) and need to resize for Instagram story format (9:16). Uploading a landscape photo to stories without resizing results in a tiny image surrounded by blurred bars. Using this tool to resize to 1080×1920 with a background fill or crop gives the story a proper full-screen result.
Social media managers — prepare client images for multiple Instagram formats
A single client photoshoot may need images prepared in three different Instagram sizes: square for the main grid, portrait for promotional posts and story size for campaign assets. Resizing all images to the correct Instagram image ratio for each format in one session — then downloading as separate files — is a repeatable workflow that ensures nothing is uploaded at the wrong size.

Complete guide — Instagram image sizes and upload best practices
Instagram image sizes 2024 — complete size guide
Instagram uses specific pixel dimensions for each post format, and uploading images that do not match these ratios causes Instagram to crop or letterbox them. Here are all the official Instagram sizes: Square post: 1080×1080 pixels (1:1 aspect ratio). The classic Instagram format — works for portraits, products and graphics. Displayed at 161×161 px in the grid, 1080×1080 in the feed. Portrait post: 1080×1350 pixels (4:5 aspect ratio). The most recommended format for feed posts — portrait images take up more vertical space in the feed than square or landscape, which increases visibility and engagement. If you are only going to use one format for feed posts, make it 4:5. Landscape post: 1080×566 pixels (1.91:1 aspect ratio). Use for wide images: panoramas, landscapes, group shots. Takes up less vertical feed space than portrait or square. Instagram Story and Reels: 1080×1920 pixels (9:16 aspect ratio). Full-screen vertical format. Images that do not fill the frame get a blurred background fill or letterboxing. Always resize to exactly 1080×1920 for stories and reels. Profile picture: Displayed at 110×110 pixels on the profile page, but upload at a minimum of 320×320 pixels. Instagram crops to a circle, so keep the main subject centered. Carousel posts: 1080×1080 pixels recommended for consistent display across slides. Mixing portrait and square in a carousel causes Instagram to crop all slides to the shortest format. File size limit: 8 MB per photo. Format: JPG is recommended for photos; PNG is accepted but Instagram recompresses it to JPG on its servers.
Why Instagram recompresses your photos — and how to minimize quality loss
Instagram recompresses every uploaded photo on its servers, regardless of the format or quality you upload. This recompression reduces file size for faster delivery on mobile networks — but it can introduce visible quality loss, particularly banding in gradients, softening in fine detail and color shifts in highlights. There are practical steps to minimize quality loss from Instagram's recompression. Upload JPG at quality 80, not at maximum quality (100). Counterintuitively, uploading an already-compressed JPG at quality 80 gives better results than uploading a large, uncompressed image — Instagram's compression algorithm produces fewer artifacts when it has less to work with. Resize the image to the exact Instagram pixel dimensions before uploading: 1080×1350 for portrait, 1080×1080 for square, 1080×1920 for stories. When Instagram has to resize an image, it applies its own resampling algorithm, which reduces sharpness. Pre-resizing eliminates that step. Avoid uploading PNG for photos — Instagram converts PNG to JPG internally, and the conversion adds an extra compression pass.
Portrait vs square vs landscape — which Instagram format gets more engagement
Format affects how much space your post occupies in the feed — and that directly affects how many users see it. Portrait (4:5, 1080×1350 px) takes up the most vertical screen space of any Instagram feed format. On a phone screen, a portrait post fills the visible area almost completely, leaving little room for other content. This increases dwell time and reduces scroll-past behavior. Studies and creator reports consistently show portrait posts outperforming square and landscape on engagement metrics (likes, saves, comments) for most content types. Square (1:1, 1080×1080 px) is the most versatile format — it works reliably for products, graphics and text-heavy images where the main subject is centered. It is a safe default when you are unsure of the content type. Landscape (1.91:1, 1080×566 px) takes up the least vertical feed space. It is the weakest format for engagement on mobile, where the feed is a vertical scroll. Use landscape only when the horizontal framing is essential to the image — wide landscapes, group shots or branded banner graphics. For most creators, the practical answer is: use portrait (4:5) for feed posts. Switch to square only when the content does not work vertically.
Frequently asked questions — resizing images for Instagram
For most feed posts, 1080×1350 pixels (4:5 portrait ratio) is the best size for Instagram. Portrait posts take up more vertical feed space than square or landscape, increasing visibility. For square posts, 1080×1080 px. For landscape, 1080×566 px. All posts should be a minimum of 1080 px wide for full resolution in the feed.
Instagram Story size is 1080×1920 pixels (9:16 aspect ratio). This is also the correct size for Instagram Reels covers. Stories and reels that are not uploaded at 9:16 ratio will have blurred bars added to fill the frame, or will be cropped.
The Instagram square size is 1080×1080 pixels (1:1 aspect ratio). Square posts are displayed at 161×161 px in the profile grid and at full 1080×1080 in the feed.
The 4:5 portrait ratio (1080×1350 px) is the best aspect ratio for Instagram feed posts — it takes up the most vertical feed space, increasing visibility as users scroll. For stories and reels, 9:16 (1080×1920 px) fills the full screen. For carousels, 1:1 square (1080×1080 px) is most consistent across slides.
Blurriness on Instagram is almost always caused by one of two things: the image was uploaded at a size smaller than 1080 px wide (Instagram upscales it, which reduces sharpness), or the image was not at the correct aspect ratio (Instagram resized it internally, applying its own resampling). Resize to the exact Instagram pixel dimensions before uploading to avoid both issues.
JPG at quality 80 is the recommended upload format for photos. Instagram converts all uploads to JPG internally — uploading PNG adds an extra compression pass that can reduce quality. Uploading a pre-compressed JPG at quality 80 gives Instagram less to recompress, typically producing a sharper result than uploading at maximum quality.
