Frequently asked questions
- Are my images uploaded to a server?
- No. All processing happens locally in your browser using the Canvas API. Your files never leave your device — you can even disconnect from the internet after the page loads.
- Which formats are supported?
- JPG, PNG, and WebP for both input and output. Quality control applies to JPG and WebP (PNG is lossless).
- Is there a file size or count limit?
- No artificial limits. Because everything runs on your device, very large batches depend on your computer's memory.
- Is it free?
- Yes — completely free, with no sign-up.
