Compress Image
Shrink an image's file size with quality and resolution controls, and compare the before/after.
What it does
Phone photos weigh several megabytes, slow down websites and break upload limits. This tool reduces file size by adjusting quality and, if needed, maximum width, and shows the new size next to the original.
A quality of 60 to 75 percent looks practically identical for photos while often cutting the file size dramatically.
How to use it
- Drop your image.
- Adjust the quality and, if needed, the maximum width.
- Press "Compress and download" and compare the new size.
When is it useful?
- Staying under a 1 to 2 MB image limit on application forms
- Speeding up website and blog images
- Attaching lots of photos to one email
- Freeing up space on your phone
Tips
- Capping width at 1600 to 2000 pixels shrinks files more effectively than lowering quality.
- Transparent PNGs get a white background when converted to JPEG; keep that in mind for logos.
Frequently asked questions
- How much does the quality drop?
- You choose the quality. Between 60% and 75% it is usually unnoticeable in photos; lower values produce smaller files.
- Which format is used?
- The output is saved as JPEG (the best balance of size and quality). Transparency in PNG inputs is turned white.
- How much smaller does the file get?
- It depends on the image. The more you lower the quality and the maximum width, the more the size drops.
- Is my photo's location data removed?
- Yes. The image is re-encoded, so EXIF data such as GPS location and device details is not carried over.
