Frequently asked questions
What's the difference between 'fit' and 'exact'?
'Fit' scales the image to fit inside your box while preserving aspect ratio — the result may be narrower or shorter than your target. 'Exact' forces the image to your exact dimensions, which can stretch or squash.
Will transparency be preserved on PNGs?
Yes. PNG outputs keep their alpha channel. JPGs get a white background since JPG has no transparency.
Can I upscale images this way?
You can, but the result will look blurry — this is bilinear scaling, not AI upscaling. For larger-than-source resizing, dedicated upscaling tools give better results.
Are my files really not uploaded?
Correct. Every conversion in this tool runs in your browser using JavaScript and the local file APIs. There is no server-side processing, no file upload, no temporary storage, and no log of what you converted. You can verify this by opening your browser's network tab while converting — the only traffic is loading the page itself.
Do I need an account or to install anything?
No. Open the page, drop your file, download the result. No signup, no email, no extension, no app.
Is there a file-size limit?
Not from us. The practical limit is your device's memory — browser tabs typically handle files in the hundreds of megabytes range without issues. Very large files may take longer to process on phones than on laptops.
