Compress any PDF to under 100 kilobytes for upload forms, government portals, and applications with strict size caps.

At 100 KB the compressor works hard. Image resolution and JPEG quality both drop to make the target fit. Text is still readable at normal zoom, but photos lose detail. A one-page text contract compresses to under 100 KB cleanly. A glossy brochure or a multi-page scan with photography often cannot hit 100 KB without visible softening.
If the Recommended quality level cannot reach 100 KB, switch to High or Maximum. Maximum drops resolution to 72 dpi, which is when text and images start to look soft. If the tool reports it cannot hit 100 KB even at Maximum, the PDF contains content that will not compress further without splitting the document first.
Drag a file into the compressor above, or click to browse. Any valid PDF works.
Choose a quality level for quick compression, or set an exact target file size in KB or MB.
Your compressed PDF is ready in seconds. The original stays untouched on your device.
Civil service exam applications, state portals, and tax forms commonly cap uploads at 100 KB for photos and document proofs.
Passport photos, ID proofs, and caste certificates often require sub-100 KB uploads on student admission portals.
PAN cards, Aadhaar copies, and signature PDFs for account opening need to fit inside tight KYC upload limits.
Scholarship portals enforce 100 KB caps to keep their databases manageable. Your signed forms need to fit.
60–80%
Scans are essentially full-page images, so the compressor has the most to work with. Contracts, receipts, signed forms all shrink dramatically.
40–60%
Charts, photos, and embedded graphics compress well. Text and tables stay untouched. The file size drops, the content stays the same.
10–20%
Already compact by nature. The compressor cleans up internal structure and metadata without any visible changes to your PDF.
Compress as many files as you want to 100 KB. Admission season, exam application rounds, scholarship deadlines. Run through every compression you need. The tool is ad-supported and costs you nothing.
The compressor above is already set to 100 KB as the target. Drop your PDF in, hit compress, download the result. For most one to three page documents, the Recommended quality level lands under 100 KB on the first pass. If the output comes back a few KB over, switch the quality level to High or Maximum and compress again.
Use the same target-size mode with 50 in the field. Getting a PDF under 50 KB is aggressive. It works for single-page text PDFs and simple black-and-white scans. Multi-page files and anything with color photos will usually fail at that target or become unreadable. If you need 50 KB, consider splitting the PDF into single pages first and compressing each one separately.
Yes. Nothing to install and nothing to sign up for. Drop the PDF above, confirm 100 KB as the target, hit compress, download the result. The compressor works the same on Windows, Mac, iPhone, and Android. Most compressions finish in under ten seconds for a one to five page file.
Switch to target size mode, enter an aggressive KB value, and let the tool run at the Maximum quality level. Combine that with the grayscale toggle if your source is in color and color accuracy is not critical. Text stays sharp, images soften. If your PDF cannot hit the target even at Maximum, that usually means the source contains scanned photography the compressor cannot shrink further without making it unreadable.
