Compress images with Lossless, Balanced, or Aggressive modes
Reduce image size for sharing and uploads. Works with JPG/JPEG, PNG, and HEIF with batch support up to 10 files.
Image Compressor
Upload up to 10 image files at a time. Each file is compressed and downloaded
automatically with a _compressed suffix. Pick a mode based on how aggressive
you want compression to be.
How this compressor works
Compress up to 10 images in one go with quick uploads and individual downloads.
This tool follows the same simple flow as the PDF compressor page. Upload a batch, let each file be
optimized one by one, and get immediate downloads with a _compressed suffix.
Upload images
Pick one or more files from your device (up to 10 at a time).
Choose compression mode
Use Lossless, Balanced, or Aggressive based on size-vs-quality tradeoff.
Individual downloads
Every compressed image is returned as its own file with a _compressed suffix.
Tip: Camera photos and screenshots usually show the best size reduction. If a file is already optimized, the final size change may be small.
Practical guide
When compression helps most and what to expect from each format.
When compression helps most
- Phone photos - camera images are often much larger than needed for sharing.
- Screenshots - repeated UI colors can compress well, especially for PNG.
- Email uploads - useful when files are just over size limits.
- Batch workflows - compress up to 10 files in one run to save time.
Best-results checklist
- Keep originals if you need untouched archival copies later.
- If size is still large, convert image format first using Image Converter, then compress.
- Very small images may show almost no reduction - that is expected.
- For maximum compatibility, JPG and PNG are the safest output formats for sharing.
- For strongest size drops on photos, try Aggressive mode.
Balanced/Aggressive: re-encode image data for stronger compression.
If a file is already tightly compressed, savings can still be limited.
Tip: If a HEIF file fails on your browser or target app, convert it to JPG or PNG and then compress.
Troubleshooting & FAQ
Answers to the most common image compression questions.

Quick glossary
A few terms you will see around image optimization.
- Lossless compression - reduces size without changing visible pixel data.
- Metadata - extra info (camera/app details) that can add file size.
- HEIF/HEIC - modern image format common on phones; efficient but not universal everywhere.
- Progressive JPEG - JPEG that loads in passes and can sometimes save bytes.
