JPEG to PNG: what changes

JPEG and JPG are the same format: .jpeg and .jpg are two extensions for identical files (the 3-letter one dates from old Windows filename limits), so any app that opens one opens the other. PNG is lossless, so editing and re-saving it never adds new artifacts, and some tools only accept PNG. Converting does not bring back detail the JPEG already lost, the PNG is usually larger, and there is no transparency: the background stays as it was.

How it works

Each file is decoded by your browser, drawn onto a canvas at its original size and re-encoded in the format you chose. Nothing is uploaded. Phone photos are rotated the right way up, and EXIF metadata (camera, GPS location) is removed. SVG files are rasterized at their own width and height. HEIC photos from iPhones are decoded on this page with libheif (compiled to WebAssembly, via the open-source heic-to library, LGPL), so they work in every browser, not just Safari. The decoder (about 0.8 MB) only downloads when you add a HEIC file. TIFF files are decoded with the MIT-licensed UTIF.js (about 80 KB, loaded only for TIFFs), and every page of a multi-page TIFF becomes its own image. The same library writes TIFF output: uncompressed baseline RGB, or RGBA with a straight alpha channel when the image has transparency you keep.

Need it smaller too? Use the image compressor (target size in KB) or resize the image to exact pixels.

Convert web pages straight to images

If your images are screenshots of web pages, skip the conversion step. The Shotmint API renders any URL or HTML in Chromium and returns a PNG, JPG or WebP directly:

curl "https://shotmint.creasework.com/v1/screenshot?url=https://example.com&format=webp&quality=80" -H "X-API-Key: YOUR_KEY" -o page.webp

Each screenshot is 1 credit. €5 buys 2,000 with no subscription, and credits never expire.

FAQ

Are my images uploaded? No. The conversion runs in JavaScript on this page, so it works for private photos and ID scans, and even offline once the page has loaded.

Does converting lose quality? To PNG: no new loss. To JPG or WebP: a little, set by the quality option. "Maximum" is visually identical for almost any image. Converting never adds back detail that was already lost.

Is there a limit? No file count limit and no watermark. Very large images (over about 50 megapixels) depend on your device's memory.

What about animated GIF or WebP? Only the first frame is converted.
