Why this stays sharp
Most online compressors turn every page into a low-resolution picture, which makes text blurry. This tool keeps your text and shapes exactly as they are and only shrinks the photos inside the PDF.
Everything runs in your browser. Your files are never uploaded.
Compress a PDF to a specific size
Choose 100 KB, 200 KB, 500 KB, 1 MB, 2 MB or enter a custom target. The compressor adjusts image quality first, then resolution only when needed.
How to compress a PDF
Select a PDF, choose a goal, start compression, review the validated result and download it only when a smaller usable file was created.
Which compression option should I use?
Use Recommended for most files, Target File Size for upload limits, and Preserve Selectable Text for text documents, links, forms and annotations.
Why scanned PDFs often become much smaller
Scanned PDFs are mostly page images. Re-encoding those images at an appropriate quality and resolution can remove much more data than structural PDF optimization.
Private browser processing
The selected PDF stays on your device. PDF.js and pdf-lib run locally in your browser, and no document upload endpoint is used.
Frequently asked questions
Can I compress a PDF to 100 KB?
Yes. Choose Target File Size and select 100 KB. Complex or multi-page PDFs may return the closest readable result instead of exactly 100 KB.
Can I choose a custom target size?
Yes. Select Custom, enter a number and choose KB or MB.
Why did my PDF not reach the exact target?
The compressor stops at a readable quality and resolution floor. When the target cannot be reached safely, it offers the closest validated smaller result.
Does Strong compression remove selectable text?
Image-based compression used by Recommended and Target File Size can flatten selectable text. Choose Preserve Selectable Text when document structure matters.
Is my PDF uploaded?
No. Compression runs locally in your browser and the PDF is not uploaded to our server.
Why is my already optimized PDF not becoming smaller?
Some PDFs already use efficient images, fonts and structure. The tool does not offer a download when it cannot create a meaningfully smaller valid file.
