How to Compress a PDF to 200KB or Any Size

Process the PDFs in your browser and download the results once the target is reached or the closest best-effort size is available.
Frequently Asked Questions
Can I compress a PDF to exactly 200KB?
The tool tries to reach your selected target as closely as possible. Exact results depend on the original PDF content, especially scanned pages and large images.
Is this browser-based PDF compressor private?
Yes. PDF compression runs in your browser, so your documents are not uploaded to our servers.
Will PDF quality change?
To reach smaller targets, the tool may reduce image detail inside the PDF. Text and layout remain readable for most everyday upload and sharing needs.
Can I compress multiple PDFs at once?
Yes. You can add multiple PDF files, compress them in one batch, and download the results together.
Can I set a custom target size such as 300KB?
Yes. Along with presets for 100KB, 200KB, 500KB and 1MB, you can enter any custom target between about 50KB and 50MB. Type your number, start compression, and the tool adjusts image quality and resolution iteratively until your file lands as close as possible to the target.
Does the compressor work on scanned PDFs?
Yes. Scanned pages are treated as images and re-encoded with adjusted JPEG quality and DPI. A 10MB scan of a certificate or mark sheet typically compresses to 500KB or below, though text pages may look slightly softer at extreme targets such as 100KB. Born-digital text stays crisp throughout.
Is there a maximum PDF file size that I can compress?
There is no server cap because your files remain on your device; the limits come from your browser memory. PDFs up to roughly 100MB or 200 pages compress smoothly on modern computers with 8GB of RAM, while older machines may struggle above 50MB.
What happens if my PDF is already smaller than the target size?
If your file is already under the target, it is passed through with light optimisation only, so it never grows. A 150KB PDF aimed at 200KB downloads essentially unchanged within seconds, and no re-encoding quality loss is introduced.
