Compress PDF to a Target Size (1 MB, 500 KB), No Upload
Set a maximum size such as 1 MB or 500 KB and shrink several PDFs at once. Built for PDFs that got heavy from photos or scans and are too big for an email or an upload form.

Select several at once (up to 30 files per batch, 150 MB and 150 pages per file). Password-protected PDFs are not supported.
1. How to shrink
Each page is redrawn as an image and recompressed as JPEG, stepping resolution (dpi) and quality down until the file fits, then the PDF is rebuilt. If even the lowest setting does not fit, the result says so and the file is left out of the ZIP. If the result would be larger than the original, the original is kept. The original title, author and other metadata are not carried over.

Results
| Original name | Output name | Original size | New size | Setting | Status | Actions |
|---|
The ZIP is built without compression (store only). If several files share a name, later ones get a suffix like -2.
Which PDFs this suits
| Good fit | Poor fit |
|---|---|
| Phone photos of documents, scans, and PDFs with pictures pasted in, where each page carries an image and the file is heavy | Text-heavy PDFs (the original is usually smaller already), and PDFs where you need selectable text, links, bookmarks or form fields |
Limits and cautions
- Pages become images and quality drops. Small text and thin lines can become hard to read. Use "Open" to check the result before you send it.
- Digitally signed PDFs lose their signature, because the file is rebuilt.
- Password-protected or damaged PDFs are not handled; the list shows the reason.
- Big pages or many pages take time. Phones can run out of memory and fail.
- Because it tries discrete steps, the result may be well under your limit.
- This does not guarantee that the file meets any particular recipient's requirements.
FAQ
Are my PDFs uploaded to a server?
Not by this page's code. Reading the PDF, redrawing the pages, recompressing and building the ZIP all happen in your browser. After the page has loaded you can turn off your network and it still works, which is one way to check. Page views are counted by cookieless Cloudflare Web Analytics, added by the host; your files are never sent. We cannot speak for your browser or its extensions.
Can I still select and search the text afterwards?
No. The tool redraws every page as an image, recompresses it as JPEG and rebuilds the PDF. Text copying, search, links, bookmarks and form fields are lost. It is not the right tool if you need a smaller file that keeps selectable text.
My text-only PDF got bigger. Why?
A PDF made mostly of text already stores that text compactly. Redrawing it as images can produce a larger file. When the result would be bigger than the original, this tool keeps your original and says so in the result table. It works best on PDFs full of photos or scans.
The result is much smaller than my target. Why?
The tool tries a ladder of resolution and quality settings and picks the highest quality that fits under your limit. The steps are discrete, so the result may land well below the limit. A file already under the limit is left untouched by default.
Will this get my PDF under an email or upload-portal limit?
It can reduce size for limits such as 1 MB, 500 KB or 25 MB. Portals and email providers set their own limits and sometimes other rules (PDF version, page count, file type), and this page does not check them. Because quality drops, open the result and make sure the text is still readable before you send it. KB here means 1,000 bytes, which is the safe way to count if the other side uses 1,024.
Can it handle password-protected PDFs?
No. Remove the password in another app first. This page does not crack or bypass passwords.
Is metadata removed?
Yes. The PDF is rebuilt from scratch, so the original title, author and creation date are not carried over. Digital signatures become invalid for the same reason.
