FileFit

FileFit is a free online toolkit for preparing images and PDFs to meet upload size, format, and dimension requirements. No account is required and files are processed right in your browser, meaning your data stays on your device and is not sent to a server.

You can choose a specific fix or use the Fit File tool to manage size, dimensions, and format in one place. Features include image compression with size limits, PDF size reduction, image resizing, format conversion for JPG, PNG, WebP and more, and PDF merging.

The tool checks actual output sizes before downloading so you can preview results and check details before saving. If a file remains too large, you can try smaller dimensions, a different format, or stronger compression.
