Question 1

Is my data safe?

Accepted Answer

Absolutely. Your images are processed entirely in your browser using the Canvas API. No files are ever uploaded to a server — everything stays on your device.

Question 2

What image formats are supported?

Accepted Answer

You can import PNG, JPEG, WebP, GIF, BMP, SVG, and AVIF images. Output formats include PNG (lossless), JPEG (lossy, great for photos), and WebP (modern format with excellent compression).

Question 3

Is there a file size limit?

Accepted Answer

There is no server-imposed limit since everything runs locally. The only constraint is your browser's available memory. Most images process without issues, but extremely large files (50MP+) may be slower.

Question 4

How does the quality setting work?

Accepted Answer

The quality slider (1-100%) controls lossy compression for JPEG and WebP output. Lower values produce smaller files with some visual loss. PNG output is always lossless, so the quality slider does not apply.

Question 5

Can I convert multiple files at once?

Accepted Answer

Yes. Drop as many images as you like and convert them all in one click. You can download each file individually or grab everything as a single ZIP archive.

Question 6

Does this work offline?

Accepted Answer

After the page loads once, the converter works without an internet connection since all processing is done in your browser. Bookmark it for quick access anytime.
