Compress PDF is the size tool in PDF Tools
This is the Compress PDF item in the PDF Tools menu — the same engine as the homepage. Choose 50 KB, 100 KB, 200 KB, 500 KB, 1 MB, or custom.
Built for shared hosting: we recompress JPEG streams inside PDFs in PHP. Best on photo/scan PDFs. Text-only PDFs may shrink less.
What you get
Mobile first
Large tap targets, one-column upload, and menus that collapse on a phone.
Auto-delete in 1 hour
Files sit outside the web root and are purged on a schedule.
No watermark
The download is your file. We do not stamp pages.
Then compress
After convert or merge, hit an exact KB cap for SSC, UPSC, and job portals.
Hostinger Cloud–ready
Runs on Hostinger Cloud with Ghostscript for exact KB compress. PHP tools work without VPS extras.
No account
No email wall. Fair-use rate limit only.

Frequently asked questions
Will Compress PDF work on Hostinger Cloud?
Yes. On Hostinger Cloud / VPS install Ghostscript (`apt install ghostscript`) and set GS_BIN=/usr/bin/gs in .env for full exact-size compression. Photo PDFs with JPEG streams still shrink in PHP even before Ghostscript is installed.
Will Compress PDF work on Hostinger shared hosting?
Partially. Shared plans usually lack Ghostscript. Photo PDFs still shrink via PHP JPEG recompress; scan-only PDFs need Hostinger Cloud with Ghostscript, or JPG to PDF then compress.
Is it safe to upload my file here?
Uploads are stored outside the public web root, addressed by unguessable names, and deleted automatically after one hour. Download links expire so a leaked URL stops working.
Is this different from Compress PDF online?
Same compressor. This slug lives under PDF Tools so the menu has a clear Compress PDF entry.
