About the Image Compressor
The Image Compressor shrinks photos and graphics so they load faster and fit under upload limits. Set a quality level and a maximum width, click Choose images, and select one file or a whole batch. Each image is scaled down if it's wider than your limit, re-encoded as WebP, and listed with its original size, new size and percentage saved, plus a Save button to download it.
Everything happens in your browser. Each image is drawn onto an HTML canvas and exported from there, so nothing is uploaded. A side effect worth knowing: re-encoding this way drops embedded metadata such as camera EXIF details and GPS location.
Who it's for. Bloggers and online sellers who want faster pages, and anyone whose email, form or marketplace rejects large files.
Reading the settings. Quality runs from 20% to 100% (default 80%). Lower values give smaller files with more visible artifacts; something in the 70–85% range is a common starting point for photos on the web. Max width accepts 200–4,096 px (default 1,920) and only ever shrinks images — a picture narrower than the limit keeps its size — with the height scaled in proportion.
Example. A 4032 × 3024 photo straight off a phone, at the default settings, is resized to 1920 × 1440 and saved as WebP at 80% quality. The results panel shows the exact before-and-after file sizes and the total saved; a large photo like this typically shrinks a lot, while an already-optimized small graphic may barely change or even grow, which the tool reports as a negative saving.
About the output. Files are saved as WebP, which keeps transparency; browsers that can't encode WebP fall back to PNG. Check that the site you're uploading to accepts WebP, as some upload forms still take only JPG or PNG. Compression is lossy, so keep your originals. Files over 50 MB are skipped.
How to use it
- Set the quality slider. Drag Quality between 20% and 100%; 80% is the default.
- Enter a max width. Type the widest size you need in pixels, from 200 to 4,096.
- Click Choose images. Select one or more image files to compress them in your browser.
- Review the savings. Check each file's before and after size and the total percentage saved.
- Save each compressed image. Click Save next to a file to download it, or Clear to start over.
Frequently asked questions
What file format does the Image Compressor save images in?
It saves WebP files, which are usually much smaller than JPG or PNG at similar visual quality and support transparency. If your browser can't encode WebP, the file is saved as PNG instead. Animated GIFs come out as a still image of the first frame.
Why did my file get bigger after using the Image Compressor?
Images that are already heavily optimized, or small flat graphics, can grow slightly when re-encoded, and the tool shows that as a negative percentage saved. Try a lower quality setting, or simply keep the original for that file.
What quality setting should I use in the Image Compressor for website photos?
Start at the default 80% and lower it while the result still looks fine to you; something in the 70–85% range is a common choice for web photos. Reducing the max width to the size the image is actually displayed at often saves more than lowering quality.
Does the Image Compressor remove EXIF and GPS data from photos?
Yes, as a side effect. Each image is redrawn on a canvas and exported as a new file, so camera EXIF details and embedded location data aren't carried over. Keep the original if you need that metadata.
Can the Image Compressor crop images or resize them to an exact height?
No. It only limits the width, scaling the height in proportion, and it never enlarges an image. Use an image editor if you need cropping or exact dimensions.
