Don't take our word for it — turn off your Wi-Fi. Docexp keeps working. A site that runs with the network off cannot be uploading your files anywhere.
Make your file fit what the form is asking for
Exact pixel size, an exact KB range — including the minimum, which is what actually gets uploads rejected and which almost every other tool ignores. Plus 115 free tools to merge, compress, and convert PDFs, photos, and documents. All in your browser; nothing is ever uploaded.
Fix a photo for an upload form →Compress an image to 100KB
Drop a photo in and it comes out at or under 100 KB — in your browser, so it is never uploaded anywhere.
What 100 KB is usually for
100 KB is the usual limit for document scans and the more generous photo slots — visa applications, university portals, and job-application attachments.
What you'll actually get at this size
100 KB is a forgiving target. A portrait at typical ID dimensions is near-indistinguishable from the original. Even a full-page scan holds up, provided you keep it greyscale — colour scans are where 100 KB starts to bite.
If your form gives a range, use both numbers. Portals often say "between 20 KB and 50 KB". Most compressors honour only the ceiling, hand you a file far under the floor, and the form rejects it for being too small. And if you also resize to the exact pixel size the form wants, the photo often lands under the minimum naturally — at which point compressing harder cannot help, because shrinking is the wrong direction. The tool below takes both ends of the range, and will raise the file back up to clear the floor.
