About FileFit Lab

FileFit Lab helps prepare photos and ordinary documents for upload. Reduce image file sizes and dimensions, turn photos into a PDF or combine multiple PDFs into one file.

Results you can check

We display actual output bytes and pixel dimensions, not made-up savings. A result over your target is labeled as such. Quality and acceptance by a recipient are not guaranteed; inspect your output before submitting it.

Processing libraries and sample credit

Resizing uses pica, PDFs use pdf-lib, and ZIP downloads use fflate. The sample photograph of Grand Teton National Park is by Alexandre Chambon, made available under CC0 on Wikimedia Commons.

Current scope

Still JPG, PNG and WebP images are supported. HEIC, animated images, PDF compression and OCR are not currently supported. Do not use this version for signed or encrypted documents.
