Why compress photos
Phone photos are often 3–10 MB each. Email attachments, job and school applications and website uploads frequently have limits of a few megabytes. Saving a photo as JPG at a lower quality removes detail you can barely see and can make the file several times smaller.
How to compress
- Choose your photos above.
- The quality is set to 70%, which usually shrinks files a lot with little visible change. Go lower for smaller files, higher for sharper ones.
- For website images, choose WebP in the format menu. It is usually smaller than JPG at the same quality.
- Press Convert. Each file shows the old size, the new size and the percentage saved.
Frequently asked questions
How small can I go?
Below about 50% you may start to see blocky patches, especially in skies and skin. Try a few settings and compare.
Does this change the width and height?
No. The image keeps its size in pixels; only the file gets smaller.
Why did a file get bigger?
If the original was already heavily compressed, or was a small PNG graphic, re-saving may not help. Keep the original in that case.
