Make a JPG smaller without losing quality
A JPG from a camera or phone is saved at a high quality, often 95 or more. That takes a lot of space and adds nothing on a screen. Saving it again at quality 75 to 85 usually makes the file 40 to 70% smaller, with no difference to the naked eye.
What happens
- The dimensions stay the same (Resize: None). Want fewer pixels too? Choose Fit in or Width.
- The JPG is compressed again at the quality you choose, progressive, so it shows right away on a website.
- Data you do not see, such as GPS, camera model and thumbnails, is removed. That saves another 10 to 50 KB per photo.
Which quality?
85 for photos that matter, 75 to 80 for websites and email, 60 to 70 when it really has to be small. Below 60, fine detail and sharp edges visibly suffer.
For a website, WEBP is another 25 to 35% smaller than JPG at the same quality. See JPG to WEBP.
How it works
Three steps to resize, optimize or convert any number of images.
Upload images
Drop, paste or pick any number of JPG, PNG, WEBP, GIF, TIFF, AVIF, HEIC or SVG files.
Choose the settings
Pick a size, format and quality. Save them as a profile so they are ready next time.
Download
Every image is processed on the server, in memory. Download them one by one or all at once as a ZIP.
Features
Powered by libvips, the same engine large photo sites use. Nothing is stored, nothing goes to third parties. The demos below are live: try them.
Resize
Set a width, a height, a percentage or a box to fit in. Give one side and the other follows the aspect ratio. "Exact" forces a size and crops the rest with smart cropping.
Need the same size for a whole batch? Drop them all at once; the settings apply to every image.
Try it: change the width on the right.
Optimize
Choose a quality from 1 to 100, or set a maximum file size in KB and let the tool find the highest quality that fits. Metadata such as GPS location is stripped by default.
Lossless mode for logos and screenshots, mozjpeg for JPG, and fine control over chroma subsampling, effort and sharpening under Advanced.
Try it: drag the line and move the quality slider.
Convert
Turn anything into JPG, PNG, WEBP or AVIF, or keep the original format. The format you pick stays selected for every image you add, no surprises.
WEBP is typically 25–35% smaller than JPG at the same quality and works everywhere; AVIF is smaller still for modern sites.
Try it: pick a format and watch the file size.
Crop
Open any image from the list and drag a crop box over it, free or locked to a ratio. Social presets for Instagram, Facebook, X, LinkedIn and YouTube set both the crop and the exact output size.
The crop only applies to that one image; everything else keeps following your global settings.
Try it: drag the box or its corners, or pick a preset.
Frequently asked questions
Does compressing a JPG again make it worse?
A little, as with every save as JPG. At quality 75 to 85 you will not see it. Always start from the original and do not compress the same file over and over.
How much smaller will my JPG get?
For phone photos usually 40 to 70% at quality 80. A JPG that is already heavily compressed shrinks less; it never gets bigger from this.
Can I change the dimensions too?
Yes. Choose Fit in, Width, Height or a percentage under Resize. That often gives the biggest saving.
Does my photo keep the right orientation?
Yes. Photos are turned upright first, following the camera, so none end up on their side.
