Results
Add an image to see its compressed size, then download it.
HOW IT WORKS
From heavy original to light download in seconds
Large images are the most common reason pages load slowly. This compressor re-encodes each image in your browser, so you ship a smaller file that looks the same, without sending your photos to any server.
Drop in your images
Add one image or a batch of JPG, PNG and WebP files. Each one is read and decoded locally on your device.
Pick quality or a target size
Slide the quality control, or switch to Target size and ask for 50KB or 100KB. Resize the longest side too if you want.
Download the smaller files
See the before and after size and the percent saved, then download each compressed image. EXIF and location data are stripped on the way out.
WHAT THIS TOOL DOES
A full image compressor, with nothing uploaded
Everything runs on the HTML canvas in your browser, so it is fast, private and works offline once the page has loaded.
JPG, PNG and WebP
Compress the three formats the web runs on. Keep the original format, or convert to WebP for the smallest files at the same quality.
Compress to an exact KB
Need 20KB, 50KB, 100KB or 200KB? Type the number and the tool searches for the setting that lands just under your limit.
Quality you control
A live before and after size and percent saved for every image, so you can trade a little quality for a much smaller file with your eyes open.
Resize while you compress
Cap the longest side to 1920px or any width you choose. Downscaling an oversized photo is often the biggest single saving.
Many images at once
Drop a whole folder of images in together. Each is compressed with the same settings and downloaded one by one.
Nothing leaves your device
No upload, no account, no queue. Your images are processed locally and re-encoding strips EXIF and GPS metadata.
IN-BROWSER VS UPLOAD TOOLS
Smaller images without handing them to a server
Most online compressors upload your files, process them in the cloud and send them back. This one does the work on your machine, so it is private by default and there is no size queue or waiting.

FAQ
Image compressor questions
Is this image compressor free?
Yes. It is free with no signup, and it runs entirely in your browser, so your images are never uploaded to a server. To find oversized images across a whole site, download the free SiteAuditLint desktop app.
Are my images uploaded anywhere?
No. Compression happens locally in your browser using the HTML canvas, so your photos never leave your device. Nothing is sent to a server and nothing is stored.
How do I compress an image to a target size like 50KB or 100KB?
Switch the mode to Target size and type the size in KB. The tool searches for the quality setting, and reduces the dimensions if needed, that brings the file just under your target.
Which format should I use, JPG, PNG or WebP?
Use JPG for photos, WebP for the smallest files when your audience uses modern browsers, and PNG only when you need transparency or sharp flat graphics. WebP is usually 25 to 35 percent smaller than JPG at the same quality.
Does compressing an image lose quality?
JPG and WebP are lossy, so very low quality settings show artifacts. The preview and the before and after sizes let you pick a setting that saves the most space while still looking clean. PNG stays lossless.
Does this remove EXIF and location data?
Yes. Re-encoding the image through the canvas strips EXIF metadata, including GPS location and camera details, so the compressed file is also cleaner for privacy.
Why compress images for SEO?
Heavy images slow pages down, and Core Web Vitals like Largest Contentful Paint reward faster loads. Lighter images improve page speed, which supports rankings and gives visitors a better experience.
