Need a size that is not here?
The compress tool takes any target you type, and the resize tool takes any width and height. These pages exist because those two questions get asked with the same handful of numbers over and over.
Common questions
Are the size tools free?
Yes, properly free. No paid tier, no trial, no watermark on the result and nothing to sign up for. Put as many files through them as you like, as often as you like.
Are my files uploaded to a server?
No. The size tools run inside your browser, on your own machine, so your files never go anywhere. Big ones are fine too, up to whatever your browser can hold.
Why does an upload form reject my photo?
Almost always the file size rather than anything about the picture. Phone cameras produce files of several megabytes and plenty of forms, especially government and school ones, cap uploads at a fraction of that. Pick the limit you were given from the list above and the image is compressed to fit it.
Do I have to know the exact pixel size a platform wants?
No, that's what these pages are for. Each one carries the size the platform actually asks for, so you can pick the page by name instead of hunting through help articles that were last updated three redesigns ago. The tool arrives already set to it.
What if the size I need is not listed?
Use the general compress tool for any file size you can name, or the resize tool for any pixel size. These pages exist because a handful of numbers come up again and again, not because the tools behind them are limited to those numbers.
