Questions and answers
- Can I compress a PDF to an exact size such as 100 KB?
- Yes. Choose a target size and the tool tries to get under it. A scanned PDF with many pictures can usually be made much smaller; a PDF that is mostly text may not shrink much.
- Will compression make my PDF blurry?
- Pictures inside the PDF are saved at lower quality to save space, so the smaller the target, the softer they look. Try a larger target first and check the result.
- Are my files uploaded anywhere?
- No. Your browser opens and processes the files itself, and nothing is sent to our servers. You can check this yourself on the How we do it page.
- Will my PDF look the same afterwards?
- Text, pictures and layout stay as they are unless the tool exists to change them, as compression does to picture quality. Check the result before you send it; your original file is never touched.
- Is Compress PDF to 20 KB really free?
- Yes. There is no sign-up, no watermark and no limit on how many files you use it for.
- Does it work on a phone?
- Yes. It works in the browser on phones, tablets and computers. A very large file can be slow on an older phone because everything runs on the device.
