Qpdf.ca looks for the best quality that fits and tells you if the target cannot be reached. Leave empty to use the level as is.

Many upload portals and email systems cap attachments at around 3 MB. This preset sets a 3 MB target and searches for the best image quality that fits, keeping text selectable. If the file cannot reach the target without unacceptable quality loss, Qpdf.ca tells you instead of pretending.
This tool runs entirely in your browser. Your file is read from your device, processed in memory, and saved back to your device — it is never uploaded to Qpdf.ca or anyone else. Once this page has loaded, the tool also works with your internet connection switched off.
