How to why is my pdf so large?

1. 1. Select a word. If you cannot, the page is a picture.
2. 2. Note which pages hold photos or scans.
3. 3. Compress those images, or export the text again from the original program.

A PDF is a container. Text, fonts, and vector drawings are usually small. Photographs and scans are not. A phone picture placed on a page can be several megabytes, and ten of those become a file people cannot mail. A “print to PDF” from a browser can also embed a huge image of the page instead of the text. Open the file and ask what you see: if you can select the words, the text is real and the size is probably pictures. If you cannot select the words, the page is a picture, and that picture is the size.

Compressing works by rewriting those pictures at a smaller pixel size and a stronger JPEG encode, then keeping the result only when it is smaller. It does not retype the document. A 2 KB text file that is “too big” is not a compression problem. A 40 MB scan is. The work this guide points to stays in the browser. No upload is required to follow it.

Why is my PDF so large? 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.
