When to use an image converter
Real use cases for image converters
Share iPhone photos on Windows and Android
HEIC photos taken by iPhones are not supported by Windows Explorer, Android or most web apps. Convert HEIC to JPG for universal compatibility before sharing.
Optimize images for web performance
WebP produces files 25–35% smaller than JPG at equivalent quality. Converting website images to WebP reduces page weight and improves PageSpeed scores.
Reduce PNG file size for delivery
Photographic PNGs without transparency are 3–5× larger than JPGs. Convert PNG to JPG to dramatically reduce file size where transparency is not needed.
Add transparency to existing images
Convert to PNG when you need a transparent-background version. PNG supports full alpha transparency — ideal for logos, icons and product images.
Maximum compression with AVIF
AVIF achieves 40–50% smaller files than WebP at the same quality. Ideal for performance-critical websites where encoding time is acceptable.
Batch convert before site deployment
Convert an entire image library to WebP or AVIF in one session. Download all results as a ZIP archive and replace the originals on your server.

Complete guide to image format conversion
Image format comparison: JPG, PNG, WebP and AVIF
Each image format has a distinct use case determined by its compression method, transparency support and file size characteristics. JPG uses lossy compression — ideal for photographs where small file size matters more than pixel-perfect accuracy. Quality 80–85 is the standard web setting. PNG uses lossless compression and supports full transparency, making it the standard for logos, icons, UI elements and screenshots. WebP is Google's modern web format — it supports both lossy and lossless modes, includes transparency support, and produces files 25–35% smaller than JPG or PNG at equivalent quality. Browser support exceeds 97%. AVIF is a newer format built on the AV1 video codec. It achieves compression 40–50% better than WebP but requires more processing time. AVIF is increasingly supported in Chrome, Firefox and Safari.
When to convert — and when to keep the original format
Convert to WebP when your goal is web delivery with the smallest possible file size. WebP is the right choice for website images, app assets and any content served to modern browsers. Convert HEIC to JPG when you need to share iPhone photos with users on Windows, Android or applications that do not support HEIC. Convert PNG to JPG when you have a photographic PNG with no transparency and need a smaller file — JPG will be 3–5× smaller at comparable quality. Convert JPG to PNG when you need to preserve an image with transparency or need lossless quality. Keep the original format when you need to maintain maximum quality for editing, or when compatibility with specific applications is required.
HEIC files explained — why iPhones use HEIC and how to convert
HEIC is Apple's High Efficiency Image Container format, introduced in iOS 11. It uses the HEVC (H.265) video codec for image compression, producing files roughly half the size of JPG at the same visual quality. iPhone and iPad cameras save photos in HEIC by default. The problem is compatibility: Windows, Android and many web applications do not support HEIC natively. Before sharing iPhone photos, convert HEIC to JPG for universal compatibility. Use the HEIC to JPG converter to convert individual photos or batch convert an entire camera roll. The JPG output is identical in quality to the HEIC source at quality 85 or higher.
Frequently asked questions
Yes. Every converter is free with no usage limits, no watermarks on output, and no credit card required.
No. All conversion runs entirely in your browser using the Canvas API and WebAssembly. Your files never leave your device.
Ceroxi supports conversion between JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, HEIC/HEIF, and SVG formats.
Yes. All converters support batch processing — drop multiple files and download results individually or as a ZIP archive.
WebP and AVIF generally produce the smallest files at comparable quality. AVIF can be 50% smaller than JPG, but conversion takes longer due to its complex codec.
JPG uses lossy compression — ideal for photographs where small file size matters. PNG uses lossless compression and supports transparency — ideal for graphics, logos and UI elements. JPG files are typically 3–10× smaller than equivalent PNG files for photographic content.
Yes, for web delivery. WebP produces files 25–35% smaller than JPG at equivalent visual quality and is supported by 97%+ of browsers. Converting website images to WebP is one of the easiest ways to improve page load speed and pass Google PageSpeed Insights recommendations.
Upload your HEIC files to the HEIC to JPG converter above. The conversion runs in your browser — no app or plugin needed on Windows. Download the JPG result and use it in any application.
No. Converting JPG to PNG preserves the existing quality but does not restore detail lost when the original JPG was created. PNG uses lossless compression, but the source data still contains JPG compression artifacts. Use PNG for new images that have never been saved as JPG.
AVIF is a next-generation image format built on the AV1 codec. It achieves 40–50% better compression than WebP at the same visual quality. However, AVIF encoding takes significantly longer than WebP. AVIF is supported in Chrome, Firefox and Safari. Use AVIF when maximum compression is the priority and encoding time is acceptable.
