LOCAL PDF COMPRESSION
Compress PDF to a target size
Choose an output size, compress locally, compare the result, then download when ready.
Reduce a PDF to a chosen maximum size
The target-size PDF compressor rasterizes pages and adjusts image quality to approach a user-entered maximum file size; the achieved size and readability depend on the source PDF.
How it works
- Select a PDF
Choose a PDF from your device and confirm that its page preview loads.
- Set the maximum size
Enter a target of at least 10 KB. The initial value is 200 KB; use the limit specified by your destination.
- Compress and inspect
Run compression, compare the displayed output size and page preview, then download only if it remains readable.
Specifications and notes
| Input | One PDF file |
|---|---|
| Target | User-entered maximum in KB; minimum accepted value is 10 KB |
| Output trade-off | Pages are rasterized; selectable text is not retained |
Privacy and processing
The selected PDF is processed by a browser Web Worker on this device. The resulting pages are raster images, so inspect legibility and verify the output against the receiving portal's rules.
Frequently asked questions
Will the output always meet the requested KB limit?
The tool attempts to meet the entered target, but compression can fail when the target is too small for the document. Check the reported final size rather than assuming a target was met.
Can I search or copy text from the compressed PDF?
No. This target-size workflow rasterizes pages, so text is no longer selectable or searchable in the output.
Does a 100 KB setting guarantee acceptance by an exam portal?
No. Portals can impose separate page, format, and size rules. Check the current official instructions and the final output file before submitting.
