PNG Converter
Convert any image to lossless PNG in bulk, with a per-file target format you can change any time, entirely inside your browser.
Why convert to PNG?
PNG uses lossless compression, so converting to it preserves every pixel of the source image exactly, with no further compression artifacts. It's the right choice when a file needs transparency, sharp text or line art, or further editing without compounding quality loss.

Features & benefits
Why this runs entirely in your browser
The conversion uses the browser's own Canvas API to redraw and re-encode each image locally, so the original files never leave the device — no upload, no server-side processing.
Common uses
Converting a batch of photos or screenshots to PNG for further editing, getting a lossless copy of a JPEG or WebP image, or preparing icons and graphics that need transparency.
Frequently asked questions
A few things people usually want to know before trusting the numbers.
Any common format — JPEG, WebP, GIF, BMP, and more — can be uploaded and converted to PNG.
Yes, up to 20 images can be queued at a time. Convert them individually, or use "Convert all" to process the whole queue, then download everything as a zip.
Yes — each row has its own format dropdown, so a single upload batch can be converted to a mix of PNG, JPG, and WebP if needed.
PNG's lossless compression typically produces larger files than JPG or WebP's lossy compression, especially for photos with lots of detail.
No. All conversion happens locally in your browser. Nothing uploaded here is sent to a server, stored, or shared.
