Reduce Image File Size
Compress
The canvas previews the compressed result live as you adjust the settings. Click Compress for the exact size and a before/after split — drag the divider to judge the quality, then download. The original file is never modified.
Your images are processed locally in your browser and never uploaded to any server.
Emails that bounce, websites that load slowly, upload forms that reject your photo. The underlying fix is the same: a smaller file. Combine quality compression with optional resolution reduction here, and watch exactly how many megabytes you saved before downloading.
How to use the reduce image file size
- Add the images that are too large.
- Choose an output format and quality, or use the target-size mode for a hard limit.
- Optionally reduce dimensions; most photos do not need more than 1920px width.
- Download your smaller images one by one or as a batch ZIP.
Frequently asked questions
What is the fastest way to shrink a photo?
Two levers matter: quality and dimensions. Dropping quality to 75–80 saves the most with no visible change; resizing an 8000px phone photo down to 1920px saves far more, since pixel count drives file size more than anything else.
How small should images be for email?
Aim for under 1 MB per image. Most email providers cap attachments around 20–25 MB total, and recipients on mobile connections will thank you. The target-size mode makes hitting a specific cap trivial.
Does reducing file size affect print quality?
Yes, if the image is destined for print, be conservative: keep quality at 90+ and avoid reducing dimensions below the printer requirements (300 DPI at the physical size). For screen use (websites, email, social), compression at 75–85 is effectively free.
