How to use the compress JPG images
- 1Press Choose images and add one or more JPG files.
- 2Pick a preset (High quality, Balanced or Small file) or move the quality slider.
- 3Check each row's new size and saving, and press Preview to compare side by side.
- 4Press Download or Download all (ZIP).
JPEG quality settings explained
JPEG quality (here 10–100) controls how coarsely the encoder rounds away fine detail. It isn't a percentage of the original quality, and the same number gives slightly different results in different programs. What matters is the shape of the curve: going from 100 to about 85 removes a lot of bytes with no visible change on most photos; below about 70 the savings shrink while blockiness, color smearing and halos around edges become easier to see.
JPEG works best on photos. Screenshots with text, logos and line art show artifacts around every sharp edge at almost any quality; keep those as PNG.
Presets: high, balanced, small
| Preset | Quality | Use it for |
|---|---|---|
| High quality | 90 | Photos you'll print or zoom into, product shots |
| Balanced | 78 | Websites, email, social posts |
| Small file | 60 | Thumbnails, previews, images shown small |
The presets just set the slider, so you can fine-tune afterwards. If a result is larger than your original (your photo was already compressed harder than the setting), the tool keeps your original file and tells you.
Removing metadata (EXIF)
Phone photos carry EXIF data: date and time, camera model and settings, and often GPS coordinates of where the photo was taken. Every image saved by this tool is re-encoded from its pixels, so none of that metadata is copied. That makes files a little smaller and safer to share publicly. The photo's rotation is applied to the pixels first, so it still displays the right way up.
If you need to keep the date taken, keep a copy of your original.
Progressive JPEGs
A progressive JPEG stores a rough version of the whole image first and refines it as it loads; a baseline JPEG loads top to bottom. Progressive files are often slightly smaller for large photos, and on slow connections they show something sooner. The browser encoders this tool uses write baseline JPEGs only, so the output is baseline. For most web images the difference in size is small; compressing to a sensible quality and resizing to the displayed width save far more.
When to switch to WebP
If the images are for your own website, WebP is usually smaller than JPEG at similar visual quality and also supports transparency. All current browsers display it. Keep JPEG when the file goes to a form, a print shop or someone who may open it in older software. To convert, use the image compressor and set Output format to WebP.
