Straight answers

Everything people ask before trusting a tool with their images.

Privacy

Do my files ever get uploaded?+

No. Every conversion, compression and resize runs in your browser. Open your Network tab and watch — nothing is sent.

What do you store about me?+

Nothing about your files. We record anonymous page views and which tools are used, with no file names, contents or sizes.

Does Under1MB strip EXIF and GPS data?+

Yes. Re-encoding an image drops its metadata, so downloads carry no camera or location data.

Using the tools

What's the difference between convert and compress?+

Convert changes the format. Compress keeps the format and shrinks the file. Convert also compresses at a smart default.

How do I hit an exact file size?+

On any compress page, type the target — for example 1 MB or 500 KB. We search for the highest quality that fits.

Can I process a whole folder?+

Drop as many files as your browser can hold and download them as one ZIP.

What does 'fit' versus 'exact' mean when resizing?+

Fit scales the image to sit inside your dimensions and keeps the proportions. Exact crops to fill them precisely.

Formats

How many formats are supported?+

11 today, across web, photo and design files.

Which formats can Under1MB write?+

PNG, JPEG, WEBP, AVIF, BMP and ICO. Formats like HEIC, GIF and SVG can be read and converted out of.

What about TIFF, PSD and RAW?+

Not yet. TIFF, TGA, PSD, PSB, CR2, CR3 and more are on the roadmap.

Why did my AVIF export fail?+

Some browsers can read AVIF but not write it. We check before you start and tell you upfront if your browser can't.

Practical

Do I need an account?+

No. There is no signup anywhere on the site.

Does it cost anything?+

No. Everything here is free and unlimited.

Does it work offline?+

Once the page is loaded, processing needs no connection at all.

Which browsers work?+

Chrome, Edge, Firefox and Safari, including iOS. Some export formats depend on your browser's own support, which we detect.

Your images. Your device. Your privacy.
