Your file never leaves this device.
Forms and portals reject PDFs over a limit. Set the size you need and get a PDF under it. Strong compression re-renders pages as pictures, which is what makes big reductions possible; light compression keeps the text selectable. Nothing is uploaded: the work happens inside your browser, on your own device.
How to use it
- Drop the PDF Scanned documents, photo PDFs and ordinary text PDFs all work.
- Choose the size and method Type the limit in KB. Use Strong for scans and picture-heavy files; Light when the text must stay selectable.
- Compress and download The result shows the new size. If a target is unreachable without making pages unreadable, you get the smallest readable version and a note saying so.
Questions
- How do I compress a PDF to 200 KB?
- Drop the file, type 200, keep Strong compression and press the button. Each page is redrawn as a JPEG at a resolution and quality chosen to bring the whole file under 200 KB.
- Why can I no longer select the text afterwards?
- Strong compression turns each page into a picture, because that is the only way to shrink a scan or a photo-heavy PDF dramatically. If you need the text, use Light compression — it keeps the text but cannot shrink pictures much.
- Why did Light compression barely change the size?
- It rewrites the file structure and removes duplicate objects. That helps files made by careless software, but a PDF that is mostly pictures is already as small as those pictures are.
- Is there a page limit?
- No fixed limit, but a very long document takes a while because every page is rendered on your device. A hundred pages is fine; a thousand-page book will take a few minutes.
- Is my PDF uploaded?
- No. The PDF is read and rewritten entirely inside your browser.
