Image Compressor That Shrinks Files in Your Browser
Drop, paste, or pick an image and shrink it with a slider. Drag the quality down, watch the output size fall in real time, then download the smaller file. It all runs in your browser, so the picture never leaves your device unless you ask for a link. Free, no account.
Whether you want to compress an image, reduce image size, or shrink a photo for email, it is the same slider-and-download here.
To compress an image, drop or paste it onto imagepaste.org, drag the quality slider while watching the output size update, then click Download. The compression runs on your device in the browser canvas, so the photo never leaves your device unless you choose to make a shareable link.

Drag the quality slider and watch the output size
Slide the quality down and the estimated output size updates live next to the preview. Stop where the file is small enough but the picture still looks good to you.

Why an image compressor that runs in your browser?
A browser-based image compressor is both faster and more private than upload-based sites. Your photo loads straight onto the canvas on your device, so it is never sent to a server while it is being shrunk. There is no upload wait before compression and no second wait to download. The smaller file is built locally and saved the moment you click. Nothing leaves your device unless you click Get shareable link. That privacy matters when the image is a screenshot, an ID, or client work that you only want to make smaller, not hand to a third party. Because the compression runs on your machine, the estimated output size updates live as you drag the quality slider, so you can balance size against how the picture looks before you commit.
How the client-side compression works
When you add an image, the browser decodes it onto a canvas in memory. The quality slider sets how aggressively the canvas re-encodes the image when it exports, which is what shrinks the file. Lower quality means a smaller file with more visible compression; higher quality keeps detail but saves less. JPEG and WebP compress the most because they are lossy formats designed for photos. PNG is lossless, so for a big size drop on a photo it often helps to export as JPEG instead. The estimated output size you see comes from re-encoding on your device as you drag. None of this reaches a server. The optional shareable link is the only step that uploads anything, and only when you click it.
Runs fully in your browser
Compression happens on the canvas on your device. No upload while you work, so there is no wait and nothing leaves your machine.
Live output size
The estimated file size updates as you drag the quality slider, so you can hit a target size without guessing.
Quality slider you control
Trade a little sharpness for a much smaller file, or keep quality high and save a little. You decide where to stop.
Good for email and upload limits
Shrink a heavy photo under an attachment cap or a form upload limit in seconds.
Optional shareable link
Need a URL instead of a file? One click uploads the compressed result and copies a short link. Skip it and nothing leaves your device.
Get a photo under an email attachment limit
A 9 MB phone photo will not send on a 5 MB cap. Drag the quality down until the size fits, then download and attach the smaller file, all without uploading the original anywhere.
Shrink images for a faster website
Oversized images slow a page down. Compress them before you upload to your site or CMS so visitors load lighter files.
Fit a form or portal upload limit
Many forms reject images over a fixed size. Reduce the file just enough to pass the limit while keeping it readable.
Save space before archiving photos
Trim the file size of a batch of photos before you store or back them up, keeping the look you are happy with.
Is the image compressor free? +
Yes, it is completely free, with no account or watermark. You can compress and download as many images as you want.
Does it upload my image? +
No. Compression runs in your browser, on your device, using the canvas. The image is never uploaded while you work or when you download. The only time anything leaves your device is if you click Get shareable link to make a URL from the compressed result.
How much smaller can it make my image? +
It depends on the picture and the quality you choose, but photos saved as JPEG or WebP often drop to a fraction of their original size with little visible change. Drag the slider and watch the live size to find the right balance.
Is the compression lossy or lossless? +
Lowering the quality is lossy, meaning some detail is dropped to save space, which is how JPEG and WebP shrink so well. PNG stays lossless, so for a big size cut on a photo it usually helps to export as JPEG instead.
What image formats can I compress? +
JPEG, PNG, GIF, and WebP all work. JPEG and WebP compress the most because they are built for photos. The download keeps the format unless you are working with a lossless one where a lossy format would shrink it further.
Is there a file size limit? +
Yes, 15 MB per image going in. That covers high-resolution phone photos and most images. The whole point of the tool is that the file coming out is smaller than what you started with.
Will I lose much quality? +
You control that with the slider, and the live preview shows the result before you download. A small quality reduction often cuts the file size a lot with almost no visible difference, so you can stop where the picture still looks good to you.
Can I compress images on my phone? +
Yes. The tool works in mobile browsers on iOS and Android. Pick a photo, drag the quality slider, watch the size drop, and download the smaller version to your device.
Does compressing change the image dimensions? +
The quality slider reduces the file size without changing the width and height. If you also want fewer pixels, crop the image first and then compress.
How do I get a link to the compressed image? +
After compressing, click Get shareable link. That uploads the smaller result and copies a short URL to your clipboard for pasting into chat, a doc, or a ticket. If you never click it, nothing is uploaded.
