This photo had already been compressed once, so the saving is modest. Camera originals usually shrink far more; for a hard size limit, use Compress to KB.

What Compress Image does
Re-encodes each image with stronger compression. JPG and WebP use the quality you set; PNGs are reduced to an optimized color palette, which is lossy but usually invisible for graphics.
When to use it
- An email or upload form rejects your file as too large.
- Images are slowing down your website.
- You want to save storage space.
Good to know
- Compression here is lossy: some detail is removed. At the default setting (75), photos usually look the same at normal viewing size.
- If a compressed file wouldn’t be smaller than the original, we keep the original and tell you.
- Switching a photo to WebP usually gives the smallest file.

Frequently asked questions
Is this lossless?
No. Lossless re-saving rarely makes photos smaller, so this tool uses lossy compression and tells you the result. For PNG-specific lossless options, use Compress PNG.
How small can I get it?
It depends on the image. If you need a specific maximum size, use Compress to KB, which searches for the best quality that fits.
What quality setting should I use?
The default of 75 is a good balance for photos. Try 60–70 when you need a smaller file for email or a website, and 85 or higher when detail matters most. The preview shows the result before you download.
Can I change the format while compressing?
Yes. Keep the original format, or save as JPG, WebP or PNG. For photos, WebP is often the smallest; for graphics with transparency, keep PNG or choose WebP.
How many images can I compress at once?
Up to 10 images per batch, 50 MB each. Download them one by one or together as a ZIP.
