Why convert JPG to PNG?

Converting JPG to PNG gives you a lossless container — useful when a pipeline requires PNG input, when you're about to edit an image repeatedly and want to stop generational quality loss, or when a tool refuses JPG. Be aware it can't restore detail the JPG compression already discarded, and the file will get larger.

Conversion happens entirely in your browser — no upload, no queue, no watermark. Drop in as many files as you like and download them individually or as a zip.

Frequently asked questions

Does converting JPG to PNG improve quality?
No — compression artifacts already in the JPG are preserved exactly. What PNG gives you is that no further quality is lost from this point on, no matter how many times the file is re-saved.
Are my images uploaded anywhere?
No. Conversion happens inside your browser using the canvas API and a Web Worker — files never leave your device. There is no upload step, no queue and no file size limit beyond your machine's memory.
Is EXIF metadata kept in the converted image?
No — and that's a feature. Re-encoding through the canvas strips all metadata: GPS location, camera model, timestamps and color profiles. The output contains pixels only, which is usually what you want before sharing an image publicly.
Can I convert many images at once?
Yes. Drop or paste any number of files; each is converted in the background with its own progress and download button, and you can grab everything at once as a .zip archive.
Why did my image get re-compressed even converting PNG to PNG?
The converter always decodes to raw pixels and re-encodes, which is also how metadata gets stripped. For lossless targets (PNG, and GIF within its 256-color limit) the pixels stay identical; for JPEG and WebP the quality slider controls the trade-off.
