Online image compression
Make photos and graphics much smaller, and check the result against the original before you save it. It all runs in your browser.
- Live before and after. Drag the divider to compare the original with the compressed image. Use zoom in and zoom out, then drag to pan, so you can check fine detail before you save.
- Updates as you adjust. Every change to quality, size or format is applied at once, and the new file size shows next to the old one.
- Auto picks the smallest format. Choose Auto (smallest) and the tool tries JPEG, WebP and PNG, then keeps whichever is smallest. Pictures with transparency keep it.
- Real PNG compression. PNG is lossless, so most tools barely shrink it. Here you can reduce it to 256, 128, 64, 32 or 16 colors with smooth dithering, the way dedicated PNG optimizers do, or keep it fully lossless.
- Hit a file size. Set a limit such as under 200 KB and the tool lowers the quality or colors just enough to fit, then tells you if it could not.
- Shrink the dimensions too. Cap the longest side at 3840, 1920, 1280 px and more. A smaller picture is often the biggest saving of all.
- Up to 50 images at once. Drop a whole folder of photos, see the total saved, and download everything as one ZIP. Your images are never uploaded.
- Never makes a file bigger. If a file is already well compressed, the original is kept instead of a larger copy.
Uses of image compression
Smaller images save time, space and bandwidth. These are the most common reasons to compress them.
- Faster web pages. Images are usually the heaviest part of a page. Smaller files load sooner, which helps visitors and search rankings. WebP at quality 75 to 85 is a good default.
- Email attachments. Most inboxes limit attachments to about 20 to 25 MB. Compress a batch of photos so they all fit in one message.
- Upload limits. Job forms, ID checks and content systems often reject files over 1 or 2 MB. Use the file size limit to fit one exactly.
- Stripping location data. Saving a new copy removes EXIF data such as GPS position and camera details, which is handy before posting a photo online.
- Freeing phone and cloud storage. Camera photos of 4 to 10 MB shrink to a fraction at no visible cost, so backups and shared albums take less room.
- Online stores. Product galleries with many large photos slow a shop down. Compress them all at once and keep them looking sharp.
- Screenshots and docs. Screenshots are PNGs and can be large. Reducing the colors keeps text readable and cuts the file a great deal.
- App and game assets. Smaller textures, icons and backgrounds mean a lighter download and faster start for your app.
Image compressor questions
How does image compression work?
JPEG and WebP save space by discarding detail the eye barely notices, and the quality setting decides how much. PNG here shrinks by using fewer colors. Lower numbers give smaller files and more visible loss, so use the compare slider to find the right point.
What quality should I choose?
Balanced (80) is a safe default and is hard to tell apart from the original for most photos. Smallest (60) suits thumbnails and web pages. Sharpest (92) keeps more detail for large prints and close inspection.
Which format is best, JPEG, WebP or PNG?
Use JPEG for photos that must work everywhere, WebP for the smallest web images, and PNG for screenshots, logos and anything needing sharp edges or transparency. If you are not sure, choose Auto and the tool picks the smallest.
Why did the file not get smaller?
It is probably already well compressed. In that case the tool keeps your original instead of making a bigger file. Try a lower quality, a smaller longest side or a different format.
Will the image lose quality?
JPEG and WebP are lossy, so there is some loss, shown in the compare view before you save. Saving as PNG with Lossless keeps every pixel. Converting a transparent image to JPEG fills the transparent area with white.
Does it remove EXIF and location data?
Yes. The picture is redrawn and saved as a new file, so camera details, GPS position and other metadata are not carried over. If the original is kept because it was already small, it keeps its metadata.
Is my image uploaded anywhere?
No. Everything runs in your browser on your own device. Your images are never sent to a server.
How many and how large can the images be?
You can add up to 50 images at a time, each up to 50 MB. Very large pictures take longer, and the limit depends on your device memory.
