How to compress an image in 3 steps
Add your images
Drop one or many images onto the page, tap "Choose images", or paste a screenshot with Ctrl+V.
Choose quality or size
Use the quality slider, or type a target size in KB. Optionally resize or convert to WebP or AVIF.
Compare and download
Drag the slider to compare before and after, then download each image or all of them as a ZIP.
Compress an image to an exact size in KB
Upload forms, job portals and government websites often accept images only up to a fixed size, such as 100 KB, 200 KB or 1 MB. Choose Target file size, type the limit, and the compressor searches for the highest quality that still fits.
If a large photo can't reach the target even at the lowest quality, it is scaled down step by step until it does. You get the sharpest result that meets the limit, not just a blurry guess.
Quality you can see before you download
Every result comes with a comparison slider: drag it across the image to see the original and the compressed version side by side. At the default quality of 75, most photos look identical to the original on screen while shrinking by 50–80%.
Lower the slider for smaller files when the image is only shown small, like a thumbnail or a profile photo. Raise it for images people will zoom into, like product photos or artwork.
Convert to WebP or AVIF for even smaller files
JPG and PNG are decades old. Modern formats store the same picture in far less space:
- WebP is typically 25–35% smaller than JPG at similar quality and opens in every current browser, on Android and on recent versions of iOS, Windows and macOS.
- AVIF is often smaller still, which makes it a great choice for websites. It takes longer to create, so expect a few seconds per photo.
- PNG stays lossless. It's ideal for screenshots, logos and images with transparency.
- JPG remains the most compatible choice for sharing photos by email or messaging apps.
Choose Same as original to keep each image's format. GIFs are saved as PNG and HEIC photos as JPG.
Resize while you compress
Phone cameras take photos of 12 megapixels or more, far larger than any screen needs. Set a max width or max height, for example 1920 pixels, and images are scaled down proportionally before compression. Images that are already smaller are never enlarged.
Resizing is the single biggest saving for photos you plan to post online or send in a chat: a 4000-pixel photo resized to 1920 pixels has about a quarter of the pixels to store.
Private by design
Images often contain more than you think: the location where a photo was taken, the device that took it, and the exact date and time. Compression runs entirely in your browser, so your images are never uploaded, and that metadata is removed by default.
There is no account, no upload queue and nothing stored on a server. Close the tab, and everything is gone.
Frequently asked questions
Is the image compressor free?
Yes. It's free with no account, no watermark and no limit on the number of images. The site is funded by a small number of clearly labelled ads.
Are my images uploaded to a server?
No. Every image is processed inside your browser on your own device. Nothing is sent to us, so private photos and screenshots stay private.
How do I compress an image to 100 KB?
Choose Target file size and type 100. The compressor tries quality levels until it finds the best one under 100 KB. If even the lowest quality is too big, it scales the image down until it fits.
Which format gives the smallest files?
For photos, AVIF is usually smallest, followed by WebP and then JPG. WebP is the safest choice when you need small files that open almost everywhere. PNG is lossless and best kept for screenshots, logos and graphics with sharp edges.
Why didn't my PNG get much smaller?
PNG is lossless, so every pixel is kept exactly. We remove wasted space, which often saves 10–40%, but bigger savings need a lossy format. Convert to WebP for screenshots or JPG for photos.
Does compressing remove location data from my photos?
Yes, by default. Location, camera model and date information is removed, which also makes files a little smaller. Untick "Remove metadata" to keep it when you save a JPG as JPG.
Can I compress HEIC photos from my iPhone?
Yes, in browsers that can open HEIC, such as Safari on iPhone and Mac. They're saved as JPG by default so they open everywhere. Other browsers can't read HEIC yet.
Can I compress many images at once?
Yes. Add as many images as you like; they're compressed one after another with the same settings. When they're done, download them individually or all together as a ZIP file.
