One file at a time for best control
Lower values shrink the file more but soften photos. Text and vector shapes stay sharp.
Four steps, one smaller PDF.
No manual required — here's the entire flow.
Add your PDF
Drop your file into the box or tap it to browse your device. One PDF at a time for precise control.
Set image quality
Drag the slider to trade image sharpness for file size. Start at 50% and go lower if you need it tiny.
Pick your extras
Toggle metadata removal to strip hidden info like author, producer, and creation dates.
Compress and download
Tap Compress PDF. Your smaller file is built on your device and ready to download in a moment.
Smaller files, same pages.
Built for the times you need to email a PDF, upload it somewhere with a size cap, or just save space.
Runs on your device
The compression happens entirely in your browser's memory. Your PDF never leaves your device.
Quality you control
Decide exactly how much to compress. Strip metadata for an extra size cut with zero visual impact.
Text stays sharp
Only embedded raster images are recompressed. Text, vector graphics, and page layout stay crisp.
Questions people actually ask.
The short answers — with the long ones one tap away.
How do I compress a PDF with this tool?+
Add a PDF file, adjust the image quality slider and toggle metadata removal if you like, then tap Compress PDF. Your smaller file downloads straight to your device — nothing is uploaded anywhere.
Are my files uploaded to a server?+
No. The compression happens entirely inside your browser using JavaScript. Your PDF never leaves your device, which also means it works without an internet connection once the page has loaded.
How much smaller will my PDF get?+
That depends on the original file. PDFs full of high-resolution images typically shrink dramatically, while text-only PDFs may only reduce slightly. The tool shows you the exact before-and-after size once it's done.
Does compressing reduce quality?+
The image quality slider lets you control the trade-off. Lower values shrink the file more but soften images. Text and vector graphics stay sharp regardless, since only embedded raster images are recompressed.
Can I compress multiple PDFs at once?+
This tool compresses one PDF at a time so you can fine-tune the settings for each document. Add your next file once the current one has downloaded.
Is this PDF compressor free to use?+
Yes, it's completely free with no account, no sign-up, and no watermark added to your compressed file.
