Compress PDF
Reduce a PDF’s file size by cleaning up its structure and recompressing its images. You see the actual size before and after, and nothing is uploaded.

US Salary CalculatorHow to use it
- Choose a PDF.
- Pick a compression level. Lossless never changes how the document looks; Balanced and Strong recompress images.
- Optionally remove document metadata such as author and editing history.
- Select Compress PDF and compare the sizes. Download the result if it is smaller.
Limits and known limitations
- Compression depends on what the PDF contains. Files that are mostly text or already optimized may shrink very little or not at all — the tool tells you when that happens instead of returning a bigger file.
- Image recompression handles JPEG images and 8-bit RGB or grayscale images. CMYK images, masked images and unusual image encodings are left unchanged.
- Fonts and vector graphics are not modified.
- The “Maximum (rasterize)” option turns every page into an image: text will no longer be selectable or searchable, and links and forms are removed.
- Encrypted PDFs need their password and are saved without one.
Frequently asked questions
Why didn’t my PDF get smaller?
PDF compression mainly works on images and redundant structure. A text-only or already-optimized PDF has little to remove. The tool reports the real result and does not pretend a reduction happened.
Will compression make text blurry?
No for Lossless, Balanced and Strong: text and vector graphics stay exactly as they are; only images are recompressed. The Maximum (rasterize) option does convert text to images.
Which level should I choose?
Start with Balanced. It usually gives a good reduction for scanned or photo-heavy documents with little visible change. Use Strong when you need the smallest size for email or uploads with strict limits.
