Questions
Will my images lose quality?
JPG, WebP and AVIF are re-saved at the quality you pick; at 70–80 most people can't see a difference. PNGs are compressed losslessly, so every pixel stays exactly the same.
Can the file get bigger?
No. If compressing would not make a file smaller, you get the original back unchanged.
What happens to HEIC photos?
They come out as JPGs, because most apps can't open HEIC.
Are my images uploaded?
No. Everything runs inside your browser on your own device. Your files are never sent to a server, and you can check: open your browser's developer tools, watch the Network tab, and you will see no upload.
Is it free? Are there limits?
Free, with no sign-up, no watermark and no daily limit. Because the work happens on your device, it costs us nothing to run, so there is nothing to ration. You can add up to 50 images at a time.
