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.
