Image compressor: reduce photo size

Make photos smaller for WhatsApp, email, websites and form uploads. Choose the quality, compress one photo or many, and download them all at once.

Private by design: images are compressed in your browser and never leave your device.

How to use it

  1. Tap Choose photos and select one or more images.
  2. Pick JPG or WebP, set the quality, and optionally a maximum width (1280 or 1920 px is plenty for screens).
  3. Tap Compress. Each file shows its size before and after; download them one by one or as a ZIP.

Where the savings come from

  • Phone cameras save at very high quality. Dropping to 70% quality removes detail you cannot see.
  • A 12-megapixel photo is 4000 px wide; most screens show at most 1920 px. Reducing the width cuts the size the most.
  • Screenshots with text often stay sharper as PNG; use the image converter if JPG makes text blurry.
  • Image resizer: Resize photos by pixels or percent, make a 35 × 45 mm passport photo, or get under 50 KB or 100 KB.
  • Image converter: Convert images between PNG, JPG and WebP in your browser, one file or many.
  • JPG to PDF: Turn photos and scans (JPG, PNG, WebP) into one PDF, A4 or fitted to each image.
  • Merge PDF: Combine several PDFs into one, in the order you choose. Files stay on your device.

Questions people ask

Are my photos uploaded to a server?

No. Compression happens in your browser using the canvas built into every modern browser. Your photos stay on your phone or computer.

What quality should I choose?

For WhatsApp, email and websites, 60 to 75% looks the same as the original to most people and is often 70 to 90% smaller. For printing, keep 85% or more.

How do I get a photo under 50 KB or 100 KB for a form?

Use the image resizer and choose “Under 50 KB” or “Under 100 KB”. It finds the best quality that fits automatically, and also handles passport-size photos.

JPG or WebP?

WebP is usually 25 to 35% smaller than JPG at the same quality and works in all modern browsers, but many government and exam portals accept only JPG. When in doubt, choose JPG.

Why did a file not get smaller?

If a photo is already well compressed, re-saving it can make it larger. In that case the tool keeps your original file. Pick a lower quality or a smaller maximum width to shrink it further.

What happens to PNG transparency?

JPG cannot store transparency, so transparent areas become white. WebP keeps transparency.
