How to Convert JPG to PNG

  1. 1Click 'Choose File' or drag your JPG image into the drop zone
  2. 2Your browser converts it to lossless PNG locally
  3. 3Click 'Download PNG' to save your file

Converting JPG to PNG gives you a lossless copy of your image — ideal for further editing, compositing, or use in projects where repeated saves would accumulate JPEG compression artifacts.

Our JPG to PNG converter runs entirely in your browser. Your image is decoded from JPEG, rendered onto an HTML Canvas, and exported as a lossless PNG. The result is larger than the original JPG but will not lose any further quality on subsequent saves.

Common reasons to convert JPG to PNG: editing in Photoshop or similar tools where multiple save cycles would degrade quality; adding a transparent layer or overlay; use in presentations or documents that require PNG format; matching a design system that requires PNG assets.

Note: Converting JPG to PNG does not recover detail lost during the original JPEG compression. PNG wraps the existing pixel data in a lossless container, but any JPEG artifacts already present in the original will remain.

Frequently Asked Questions

Does converting JPG to PNG improve the image quality?⌄
No. PNG is a lossless container, but it can only preserve the quality that's already in the JPG. JPEG compression artifacts that existed in the original will still be present in the PNG output. However, future edits won't add any new artifacts.
Why is the PNG larger than the original JPG?⌄
PNG uses lossless compression. It stores all pixel information without discarding any, so the files are inherently larger than JPEG for photographs. This is the tradeoff for lossless quality.
Is it really free? Are there any limits?⌄
Yes, completely free with no limits. You can convert as many files as you want, as large as your device's memory allows. We don't have a server to run, so we have no reason to charge or impose limits.
Do you upload my files to your server?⌄
No. All conversions happen locally in your browser using the browser's built-in image APIs. Your files never leave your device. We do not have servers that process files — by design, not by promise.
What is the maximum file size?⌄
There is no hard limit set by us. The only constraint is your device's available memory. Most modern devices handle files up to several hundred megabytes without any issues.
Do I need to create an account?⌄
No account required. We don't have a user system. Open the page, drop your file, download the result — that's it.
