Image converter
JPG, PNG and WebP to each other with no change in resolution. Quality control for JPG and WebP; transparent PNG to JPG gets a white background. The file is processed in your browser and never uploaded.
New format
Resolution stays the same: the image is saved at its original size.
92% is the sweet spot: no visible loss, noticeably smaller file. 100% is maximum quality and the heaviest file.

How to convert an image
Choose a file or drop it into the box on the left — the tool shows the current format, resolution and size. Pick the new format, adjust the quality slider for JPG or WebP if needed and check how big the result will be. Then click “Download image”.
Need to change the size? Use the image resizer with cover art presets. Starting from scratch? Browse ready-made cover art in the catalog.
Nowhere. Conversion runs right in your browser with the Canvas API: nothing is uploaded to a server, and nothing remains once you close the page.

92% is the sweet spot: visually identical to the source with a noticeably smaller file. 100% is maximum quality and the heaviest file; use it if your distributor asks for uncompressed JPG cover art. PNG is lossless and has no quality setting.
No. The image is saved at its original size; only the file format changes. If you need a different size, use the image resizer.
Distributors accept JPG and PNG, usually 3000×3000 px in RGB. WebP isn’t accepted for cover art: convert it to JPG or PNG.
