How to compress an image
- Add your images by dropping them above, clicking "Choose files" or pasting.
- Lower the quality until you are happy with the file size shown for each image. The results update instantly.
- Resize big photos (optional): phone photos are often 4000+ px wide, and 1920 px is plenty for screens.
- Download each image or all of them as a ZIP.
Tips for the smallest files
- Choose WEBP for websites: it is typically 25–35% smaller than JPG at the same quality.
- Resize before you compress: halving the width cuts the pixel count, and usually the file size, by about 75%.
- Use JPG for photos, PNG for graphics: photos saved as PNG are often 5–10× larger than necessary.
Frequently asked questions
How much can I reduce the file size?
Photos usually shrink by 50–80% at quality 75 with no visible difference. Combining compression with resizing (for example to 1920 px wide) often reduces large phone photos by 90% or more.
Which quality setting should I use?
Use 80–85 for photos where quality matters, 70–75 for websites and email, and 50–60 when the smallest possible file is more important than fine detail.
Can I compress PNG files?
PNG is lossless, so the quality slider does not apply. To make a PNG smaller, resize it or convert it to WEBP (which keeps transparency) or JPG (for photos without transparency).
Why did my file get bigger?
If the original was already heavily compressed, re-encoding at a higher quality can make it larger. Lower the quality slider or resize the image to get a smaller file.
Are my images uploaded to a server?
No. All conversion happens inside your browser on your own device. Your photos are never uploaded, stored or seen by anyone, which also makes conversion faster and lets it work on any connection.
Is it really free? Are there limits?
Yes, it is completely free with no sign-up and no watermark. Because nothing is uploaded, there are no file size or file count limits. Very large batches are only limited by your device's memory.
Can I convert many images at once?
Yes. Select or drop as many images as you like. They are converted in parallel, and you can download them one by one or all together as a ZIP file.
Is the photo metadata (EXIF) kept?
No. Converted images do not contain the original metadata such as GPS location, camera model or date. This protects your privacy when sharing photos. The orientation is applied, so photos stay the right way up.
