PDF Compressor

Make a PDF smaller by rebuilding its pages at a lower resolution — great for scans.

About the PDF Compressor

The PDF Compressor shrinks a PDF by rebuilding each page at the resolution you choose: Screen (96 DPI) for the smallest file, eBook (150 DPI) for a balance of size and clarity, or Print (220 DPI) when the document still needs to look sharp on paper. This works best on the files that are usually too big — scanned documents and photo-heavy PDFs — often cutting them to a fraction of their original size so they fit email and upload limits.

How to use it

  1. Choose a PDF or drop it onto the box.
  2. Pick a compression level — eBook is a good starting point.
  3. Press Compress PDF and watch the progress.
  4. Compare the original and compressed sizes, then download.

Frequently asked questions

Why does the compressed PDF's text stop being selectable?

To make pages smaller, this tool rebuilds each page as a JPEG image, so the text becomes part of the picture — readable, but not selectable or searchable. Keep your original file if you need searchable text.

Which level should I choose?

Screen gives the smallest file and is fine for reading on phones. eBook balances size and clarity for sharing. Print keeps the most detail for documents you will print.

Why did my PDF not get much smaller?

A PDF that is already mostly text with few images has little to compress — image-based rebuilding mainly shrinks scans and photo-heavy documents. Try the Screen level for the biggest reduction.

Is my document uploaded to a server?

No. Compression runs entirely in your browser — your PDF never leaves your device.

Shrink JPG, PNG and WebP images with a quality slider and live size comparison.

About the Image Compressor

The Image Compressor re-encodes your picture at the quality, maximum width and output format you choose, then shows the compressed file size next to the original so you can see exactly how much you saved before downloading. Smaller images load faster on websites, fit inside email and upload limits, and take up less storage — and because everything runs on your device, your photos are never uploaded.

How to use it

  1. Choose an image or drop it onto the box (JPG, PNG or WebP).
  2. Set the quality, and optionally a maximum width and output format.
  3. Compare the original and compressed sizes and check the preview.
  4. Download the compressed image — or Remove it and try different settings.

Frequently asked questions

Are my images uploaded to a server?

No. Compression runs entirely on your device inside the browser. Your image never leaves your phone or computer, which also makes it fast.

What quality setting should I use?

Around 80% is a good default for photos — a much smaller file with little visible difference. Go lower for thumbnails and previews, higher when fine detail matters.

Can I shrink an image's dimensions as well?

Yes. The Max width option scales large photos down to 1920, 1280 or 800 pixels wide, which is often where the biggest file-size savings come from.

Which output format makes the smallest file?

JPEG is usually smallest for photos, WebP is smaller still in browsers that support it, and PNG is best kept for graphics that need transparency or perfectly sharp edges.
