1 Add the PDF. This page already sets the goal at 10 MB.2 Compress on this device. Text is not rewritten. Images shrink only while the new file is smaller.3 Read the size your system reports. If it is above 10 MB, that is the floor for this file, not a failed upload.
About this tool
Ten megabytes is a ceiling for a big packet, not a diet. A photo set or a long color scan can aim here so it moves more politely without looking like a thumbnail. A 12 MB file that is “all text” usually hides images or a broken export; Repair PDF or a fresh export may matter more than another squeeze. Ten megabytes will not make a 200-page scan tiny. It makes an oversized one less oversized.
Compress PDF to 10 MB stays on this device. The download is the copy you keep, and Weesize does not store a second one. Close the tab when you are finished and the bytes are gone.
- No upload: the 10 MB goal is applied here, and the PDF is not posted to a compressor.
- Speed: the file does not travel to a server and back, so the wait is only the work itself.
- Quality: the original is kept when the new file would be worse or is not actually smaller.
