Frequently asked questions

Are these image tools free?

Yes. Every tool on Filekind is free with no signup, no watermark, and no daily limit. They run in the browser, so there is nothing to install.

Do I have to upload my photos?

No. Images are read and processed on your device with JavaScript. Your files are never sent to a server, which also means the tools keep working with private or sensitive pictures.

Which image formats are supported?

JPEG, PNG, and static WebP. You can convert between all six combinations, compress JPEG and PNG, resize any of them, and place them into a PDF.

What are the limits?

Images are limited to 25 MB, 16,000 pixels per side, and 48 megapixels. Those limits keep unusually large photos bounded while still covering high-resolution cameras.
