About this tool
Most online forms, from SSC and UPSC to passport and scholarship portals, reject PDFs above a fixed size. A normal compressor only makes the file "smaller", so you keep guessing. This tool works backwards from your limit: it tries lossless compression first, then finds the highest image quality that still fits under the size you chose.
Frequently asked questions
Will my PDF stay readable?
We always pick the highest quality that fits your limit. For very small limits on long documents, text can get soft; removing extra pages usually helps.
What if my PDF is already small enough?
You get your original file back unchanged, with a note that no compression was needed.
Why are pages saved as images?
Only when lossless compression is not enough. Turning pages into optimized images is the only reliable way to hit strict limits like 50 KB or 100 KB.
Are my files uploaded to a server?
No. Compress PDF to exact size runs inside your browser, so your document never leaves your phone or computer. Close the tab and nothing is kept.
Is Compress PDF to exact size free?
Yes. You can use it free without creating an account. Premium removes file-size and batch limits for heavy users.
Does it work on mobile?
Yes. It works in Chrome, Safari and every modern browser on Android, iPhone, Windows and Mac. You can also install Pixel Path PDF as an app from your browser menu.
