Compress a PDF in your browser with Rewrite or Stronger
The PDF stays in this browser. Rewrite keeps selectable text. Stronger re-renders pages as images so scans can shrink. Limit 25 MB and 200 pages. One file at a time.
Runs in your browser. No signup required.
A PDF can grow for reasons that have nothing to do with how many pages you see. Editors leave unused objects behind, and some exports store the same font or image data more than once. This compressor runs in your browser. You choose Rewrite or Stronger after you see the page count and the original size.
Rewrite rebuilds the file and keeps the pages in order. Words you can select stay selectable when the original allowed it. It does not photograph each page or turn text into a picture. A file that is already tightly packed may barely change, and a stack of scans will not shrink. Compare the sizes and the percent saved, and keep the original if the rewrite is larger.
Stronger re-renders each page as a JPEG and builds a new PDF. Use it when a scan or a photo-heavy file is too big to send. Small, Balanced, High, and Archive set the resolution and JPEG quality. The slider picks a quality from 10 to 95, and a lower number is a smaller or equal file. Text in a Stronger file is a picture, so you cannot select it. After it finishes, the page shows a first-page preview.
Nothing is uploaded. The tool refuses a file over 25 MB, a file that is not a real PDF, and a file that will not open. Password-protected files fail closed instead of being guessed. Documents with more than 200 pages are refused so the tab does not run out of memory. One file is processed at a time. There is no promised percent and no target file size. Split PDF can pull out the pages you need, and PDF to Word can lift selectable text. Keep the original until you have compared the two sizes.
Shrink a PDF’s file size free in your browser with Rewrite or Stronger compression.
Open the compress PDF page.
Choose one PDF. The page shows the file name, page count, and original size. The file stays in the browser.
Choose Rewrite to keep selectable text, or Stronger to re-render each page as an image.
On Stronger, pick Small, Balanced, High, or Archive, or move the quality slider from 10 to 95. Rewrite has no slider.
Click Compress PDF. Compare the original size, the compressed size, and the percent saved. Stronger shows a first-page preview.
Click Download PDF. Keep the original if the new file is not smaller.
Choose Rewrite if you need selectable text. It rebuilds the PDF in your browser and does not turn pages into pictures. Choose Stronger for scans and photo-heavy files: it re-renders each page as a JPEG, with Small, Balanced, High, and Archive presets plus a quality slider from 10 to 95. Compare the sizes and the percent saved, then download. Keep the original if the new file is larger. Stronger text is an image, so it is not selectable.
Yes for UtilGenie’s browser-side flow: Rewrite and Stronger both run on your device, so the PDF isn’t sent to UtilGenie servers for compression. Still avoid sharing passwords or secrets in any online UI you don’t trust.
Savings depend on the file and the mode. Rewrite can shrink a loose digital PDF and may leave a compact file about the same size. Stronger usually shrinks scans by lowering JPEG quality, and a lower quality is a smaller or equal file. There is no target-size control and no promised percent. The limit is 25 MB and 200 pages.
Compress PDF shrinks file size. Split PDF separates or extracts pages. Use compress when the file is too big; use split when you need fewer pages or separate files.
