Common questions
Photo resizing and compression FAQ
How do I reduce a photo to under 100 KB for an online form?
Choose the photo, enter a requirement such as “JPG under 100 KB”, then prepare and download it. JPEG and WEBP quality is reduced locally until the result approaches the requested limit.
Does WhatTheFile upload or store my photo?
No. Current image processing happens inside your browser. The selected photo and prepared download are not sent to WhatTheFile servers.
Can I resize a passport or application photo to exact dimensions?
Yes. Enter pixel dimensions such as “600 × 600 JPG”. The photo is centre-cropped to the requested aspect ratio so it is not stretched.
Which image formats are supported?
WhatTheFile accepts JPG, PNG and WEBP images and can convert between those formats. JPG or WEBP is usually best when a strict file-size limit matters.
Can WhatTheFile compress PDFs?
Not yet. It can privately check whether a PDF already meets a file-size limit, but PDF recompression is still planned.
