Compress PDF for Upload
Every portal has a gate: 200KB here, 1MB there, 2MB elsewhere. Whatever the number, enter it as the target and clear the gate first try — with the true size shown before you submit. We compress toward your target at the best quality that fits, never make the file larger than the original, and always show the real final size — very image-heavy files may land slightly above tight targets.

The upload-rejection loop, ended
The familiar cycle — upload, reject, guess a compression setting, repeat — exists because generic compressors do not aim. Target-based compression aims: state the portal's limit, get a file under it, upload once.
Read the requirement precisely
Portals specify limits per file, sometimes per page, occasionally combined. Match the target to what the field actually says — and aim slightly under for strict-measuring systems.
