Compress PDF
Most PDF sites receive your file on their servers to compress it there. RahaKit works the opposite way: your PDF is compressed entirely inside your browser, so the document never leaves your computer and nothing is uploaded to us. Choose High quality for the lightest touch, Balanced for everyday documents, or Smaller file for the strongest compression — images inside the PDF are recompressed at the level you pick, while text and vector content are left untouched.
The password is used only on your device to open the file. It is never stored and never sent anywhere.

How to compress a PDF
- Drop your PDF into the box, or click to browse and select it from your device.
- If your PDF is password-protected, enter its password. It is used only on your device and never stored or sent anywhere.
- Pick a compression level: High quality, Balanced, or Smaller file.
- Click Compress PDF.
- Compare the original size and the new size shown side by side.
- If the file isn't smaller, the tool says so plainly — your original on disk is never changed either way.
- Download the compressed file, saved as <original name>-compressed.pdf.
Why this tool is different
Most PDF sites receive your file on their servers and compress it there, which means a copy of your document sits on someone else's computer. This tool works the opposite way: the compression happens entirely inside your browser, using your own device's processing power. Your file is never uploaded, never stored, and never seen by anyone but you. You can check this yourself: open your browser's Network tab while you compress and you will see no upload of your file.
Good to know
Images carry the weight
Almost all of a PDF's size is its images. Text is tiny by comparison, which is why image-heavy files shrink the most and text-only files barely change.
Text and layout never change
Compression recompresses images and rebuilds the file structure. The words, the layout and the page count stay exactly as they are at every level.
An honest result, every time
You see the original size and the new size side by side before you download. If compressing did not make the file smaller, the tool says so plainly and offers no download — it never dresses a bigger file up as a compressed one.
Examples
| What you have | What you add | What you get |
|---|---|---|
| A scanned contract | One PDF, image-heavy | The same PDF, much smaller — ready to email |
| A photo document | Photos saved as a PDF | A smaller PDF that still looks right on screen |
| A text-only report | A report made of text | About the same size — and the tool tells you so |
Common mistakes
Expecting every PDF to shrink
A text-only PDF has almost nothing to compress — its size is already close to the minimum. The tool shows both sizes honestly instead of promising a saving that is not there.
Choosing Smaller file for a print document
The strongest level softens images the most. If the PDF is going to print, pick High quality; if it is only going on a screen or into an email, Balanced or Smaller file is fine.
Closing the tab before downloading
The compressed copy exists only in this tab's memory. Download it before you close the tab; your original file is never changed.
Compress PDF — questions
Where does my file go?
It stays on your computer. Your PDF is read into your browser's memory and the compressed copy is built there — nothing is uploaded to us, nothing is stored on a server, and no file data is passed to analytics. You can check this yourself by opening your browser's Network tab while compressing: no upload of your document takes place.
How much smaller will my PDF get?
It depends on what's inside the file. Image-heavy PDFs, like scans or photo documents, usually shrink the most, because images carry almost all of a PDF's weight. A text-only PDF may come out about the same size, and a file that's already tightly compressed may not shrink at all. The tool shows you the original size and the new size side by side, and if the new file is not smaller, it says so plainly — it never offers a bigger file as the result.
Does compression change the quality?
The images inside the PDF are recompressed at the level you choose, so High quality applies the lightest touch and Smaller file applies the strongest. Text and vector content are not touched, so words, lines and drawings stay sharp regardless of the level.
Will compressing change my text or layout?
No. Compression only recompresses images and rebuilds the file in a tighter structure — it never changes the words, the layout, or the page count.
Can I compress a password-protected PDF?
Yes. Enter its password when the tool asks so the PDF can open on your device. The password is used only in browser memory, never stored, and never sent anywhere. The compressed copy is unlocked, so it will no longer require the original password to open.
Is Compress PDF free and unlimited?
Yes. It is completely free and unlimited: no account, no daily limits, no watermarks and no page-count cap from us. Your files are processed on your own device, so the only practical limit is your device's memory.
Your file stays yours
The file is read into your browser's memory and processed there by code that runs on your device. Nothing is uploaded, nothing is stored, and no file data is logged or passed to analytics. The tool does not edit, enhance or recognize anything inside your document; it only recompresses the images and rebuilds the file. When you close the tab, everything is gone. If the PDF is one you would not email to a stranger, it is safe to compress it here.
