Convert any image to PNG online free — no upload, no account, no daily limit. Drop your files and download lossless PNG output with full transparency support. Supports JPG, WebP, HEIC, AVIF, GIF, BMP, TIFF and SVG in the same batch.
Unlike cloud-based converters that send your files to a server, everything here runs directly in your browser using the Canvas API. No upload wait, no privacy risks, no usage cap — convert as many images to PNG as you need, at full resolution, completely free. PNG output is always lossless: no compression artifacts, no quality loss.

Who uses this online PNG converter
Designers — lossless assets for Figma, Photoshop, Canva
Perfect for ecommerce, social media, and marketing teams. Design workflows require lossless source files. PNG is the standard for logos, icons, UI components, illustrations and any asset that will be resized, masked, composited or exported multiple times. Converting source files to PNG before importing into design tools ensures no compression artifacts appear during the workflow. Works for converting WebP downloads, HEIC iPhone photos and JPG source files to lossless PNG in one step.
Developers — convert images to PNG without losing quality
Web and app development often requires PNG for UI assets: icons, buttons, overlays, watermarks and any element that needs transparency. Converting existing assets from WebP, JPG or other formats to PNG produces standard, universally compatible files that work in every browser, framework and build tool. SVG-to-PNG rasterization is also supported for generating PNG fallbacks from vector sources.
Content creators — transparent overlays and cutouts
YouTube thumbnails, Instagram posts, presentation slides and marketing materials regularly use images with transparent backgrounds — logos placed over custom backgrounds, cutout subjects layered over scenes, watermarks overlaid on photos. PNG is the correct format for all of these. Converting existing WebP or GIF transparent assets to PNG ensures they work in every application from Canva to Google Slides to video editing software.
Anyone who needs maximum image quality online
Converting image to PNG online without losing quality is the main promise of lossless conversion. For professional headshots, product photos destined for retouching, artwork and illustrations, medical images and any content where pixel accuracy matters — PNG is the format that guarantees nothing is lost. Convert from HEIC, WebP, AVIF or any source format to get a lossless PNG that preserves the original data exactly.
Why this is the best free online PNG converter
Lossless output, transparency preservation, and privacy-first processing — all free, all in-browser.
PNG preserves every pixel — no compression artifacts
PNG uses lossless compression: the output file is pixel-perfect identical to the source, with no JPEG-style artifacts, no color shifts and no edge blurring. This makes PNG the correct format for screenshots, logos, UI graphics, text-heavy images, diagrams and any content where sharpness matters. Every conversion produces a PNG that is visually indistinguishable from the original — because lossless means exactly that.
Full alpha channel support — transparent backgrounds included
PNG supports a full 8-bit alpha channel, meaning every pixel can have its own opacity level from fully transparent to fully opaque. When converting from WebP, GIF or other formats that carry transparency, the alpha channel is preserved in the PNG output. This is essential for logos, cutout images, UI elements and any asset that needs to work on different colored backgrounds without a white rectangle around it.
Your images never leave your device
Every conversion runs locally in your browser using the Canvas API and JavaScript. No image is uploaded to any server, transmitted over the network or stored anywhere. The tool works without an internet connection after the initial page load. This makes it safe for converting personal photos, confidential design assets, client files, medical images and any content you cannot let touch a third-party service.
