Convert images to PNG
PNG is the safe choice when you need transparency or a lossless copy — a logo, a screenshot, an image going into a document.
- Runs entirely in your browser
- Works offline
- No upload
- No sign-up
- No watermark
Loading the tool…
How it works
- Drop your images.
- PNG is already selected; add a resize if you need one.
- Convert and download.
Why nothing is uploaded
Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.
Verify it yourself
- Open your browser’s developer tools (F12) and select the Network tab.
- Load your file and run the tool.
- The only requests you will see are the tool’s own code and, once cached, none at all.
Frequently asked questions
Will PNG make my photo bigger?
Almost certainly, and often several times bigger. PNG is lossless, so it cannot throw away detail the way JPG does. For photographs keep JPG or WebP; use PNG for graphics, logos and screenshots.
Does transparency survive?
Yes, from any format that has it (WebP, AVIF, GIF, SVG). Going the other way into JPG it cannot: JPG has no alpha channel, so transparent areas are filled with the background colour you choose.
Are the images uploaded to convert them?
No. The image is decoded by your browser, redrawn on a canvas and re-encoded there. Load the page, switch your connection off and the conversion still works — that is the proof.
Is there a size or batch limit?
None that we impose. Drop a hundred files if you like; they are processed one after another with a progress bar, and the ceiling is your device’s memory.
What happens to EXIF and GPS data?
It is dropped by default, which is usually what you want before sending a photo to anyone. Tick “Keep EXIF” if you need the capture date and camera preserved in a JPEG output.
