Free Image Compressor

Why compress images?

Photos from modern phones are often 3MB to 8MB each. That is far more than most uses need. Large images:

• Fail upload limits on forms, job portals and email (many cap files at 1MB or less).
• Slow down websites, which hurts visitors and Google's Core Web Vitals.
• Fill up phone storage, cloud drives and WhatsApp backups.
• Use more mobile data when you share them.

Good image compression removes detail your eyes cannot see. A 4MB photo often becomes 300–600KB at 80% quality and looks the same on screen.

What this compressor can do

• Batch compression: add many images at once and see the saving for each.
• Quality slider: from 30% (tiny files) to 100% (maximum quality).
• Target KB mode: type a size such as 100KB, and every image is compressed to fit under it.
• Resize while compressing: limit the width to 1920, 1280 or 1080 pixels for web and social use.
• Format choice: keep the original format, or convert to JPG or WebP.
• Download one or all: each file is named with "-compressed" so the original stays safe.

Steps to compress images online

• 1
  Add images

  Choose JPG, PNG or WebP files, drag them in, or paste a screenshot. You can keep adding more.

• 2
  Pick quality or a KB limit

  80% suits most photos. Turn on "Target size" if a website or form gives a KB limit.

• 3
  Optionally resize and convert

  Choose a maximum width and output format. The list updates automatically.

• 4
  Download

  Click ⬇ next to an image, or "Download all".

Which quality setting should you use?

JPG, PNG or WebP?

• JPG is best for photos and is accepted everywhere.
• PNG is lossless, so the quality slider does not apply. Use it for logos and screenshots with text. To shrink a PNG photo, convert it to JPG or WebP.
• WebP is usually 25–35% smaller than JPG at the same quality and supports transparency. Google recommends it for faster websites. See Google's WebP page.

Tips for the smallest files

• Resize before you compress. A 4000-pixel photo shown at 1200 pixels wastes bytes. Set a maximum width.
• Avoid compressing the same JPG again and again. Start from the original each time.
• Use WebP for websites and JPG for forms that only accept JPG.
• For an exact KB size, use the KB Resizer. For exam photos, use Photo to 50KB or the SSC Photo Resizer.

Private and unlimited

There is no limit on the number of images and no watermark, and your photos never leave your phone or computer. Learn more about image compression.
