How to compress a PDF
- Tap Choose file and pick your PDF.
- Leave the mode on Recommended. It shrinks the photos and scans inside the PDF and keeps the text sharp and selectable.
- Pick a level: High is a good balance, Extreme gives the smallest file, Low keeps the best quality.
- Need an exact limit? Type it in Target size in KB, for example 100 or 200.
- Press Compress PDF and download the smaller file.
Reduce PDF size for exam and job forms
SSC, Railway, bank, state PSC and university portals often accept PDFs only up to 100 KB, 200 KB, 300 KB or 1 MB. A scanned certificate from a phone is often 2 to 8 MB. Type the limit from your notification into the target box and the tool keeps trying stronger settings until the file fits, so you do not have to guess.
Recommended or Strong mode?
- Recommended keeps text as text. Use it for typed documents, forms, resumes and reports.
- Strong turns every page into a JPEG picture. It gives the smallest file for scans and photos, but the text can no longer be selected or copied.
- If a PDF is already well optimized, the tool tells you and returns the original instead of making it bigger.
Safe for private documents
Compression happens inside your own browser. Your file is not uploaded to our server, so Aadhaar copies, marksheets, bank statements and office papers stay on your phone or computer. There is no sign-up, no daily limit and no watermark, and it works in Chrome, Edge, Firefox and Safari on Android, iPhone, Windows and Mac.
Tips
- Joining several scans? Merge them first, then compress the single file once.
- Remove pages you do not need with Delete PDF Pages. Fewer pages means a smaller file.
- Have photos, not a PDF? Make the PDF with JPG to PDF and then compress it.
Frequently asked questions
How do I compress a PDF to 100 KB?
Choose your PDF, type 100 in Target size in KB and press Compress PDF. For a scan with many pages, Strong mode may be needed to reach a very small size.
Will compression reduce the quality?
Recommended mode only shrinks the pictures inside the PDF, so text stays sharp. Photos become a little softer at the Extreme level.
Can I compress a PDF on my phone?
Yes. It works in the browser on Android and iPhone with no app to install.
Are my files uploaded to a server?
No. The file is processed inside your browser and is never sent to our server.
Why did my PDF not get smaller?
A PDF with only text and no pictures is already small. In that case the tool returns your original file. Try Strong mode if you must go smaller.
Is there a file size limit?
There is no fixed limit. Very large files depend on your device memory and take longer on older phones.
