Compress PDF
Shrink PDF file size with Ghostscript-powered compression — keep the quality you need.
What is Compress PDF?
PDF compression reduces a PDF's file size by downsampling its images, subsetting embedded fonts, and stripping redundant objects — while keeping the text and layout readable. NewKitApp runs compression server-side with Ghostscript, the same industrial-strength engine publishers and print shops rely on, so it can shrink PDFs far more aggressively than browser-only tools, which can only re-save a file without ever touching the resolution of the images inside it.
How to Use Compress PDF
- Drag your PDF onto the dropzone, or click to choose a file.
- Pick a compression level — High compression for the smallest file (email/screen), Balanced for everyday use, or Best quality for near-original fidelity.
- Click Compress PDF. The file is processed on the server and a download link appears in a few seconds.
- Download the result right away — the link expires after about 10 minutes and the file is deleted immediately after processing.
Examples
Email-friendly résumé
Input: 8.4 MB scanned résumé
Output: ~1.1 MB at High compression — fits any inbox
Readable ebook chapter
Input: 6.0 MB chapter with photos
Output: ~1.8 MB at Balanced — text crisp, images lightly downsampled
Common Mistakes
- Choosing High compression for a document you plan to print — the 72 dpi images look soft on paper. Use Balanced or Best quality instead.
- Expecting big savings on text-only PDFs — with no images to downsample, the reduction is modest.
- Forgetting the download link expires in about 10 minutes — save the file as soon as it's ready.
Why Use This Tool
- Ghostscript-grade compression browser tools can't match — real image downsampling plus font subsetting.
- Three clear presets tuned for email, everyday use, and high-fidelity output.
- Text stays razor-sharp at every level; only images are affected.
- Files are processed and deleted automatically — no permanent storage, no account required.
