Why Use Our Image Compressor
Big image files slow pages and uploads down. This tool makes them smaller, with little visible quality loss at normal settings.
Shrink Files Way Down
Images typically get 50-80% smaller. A 5MB photo can become about 1MB, so pages load faster and uploads finish sooner.
Do a Bunch at Once
Got 20 photos that need compressing? Upload them all together. We'll handle them all at the same time and give you everything back in a ZIP file.
Still Looks Good
We use smart compression. Your eyes won't spot the difference between the original and compressed version, but the file size difference is huge.
Your Photos Stay Private
Everything's encrypted when you upload. We compress your images and then delete both the originals and compressed versions after an hour. We do not look at your images.
Works With Common Formats
JPG from your camera, PNG screenshots, WEBP graphics - we handle all of them. Whatever image format you've got, we can make it smaller.
Makes Websites Faster
Smaller images mean pages load in a flash. Good for your visitors, good for Google rankings. If you run a website, this is a must-have tool.
Three Quick Steps
Upload, compress, download
Upload Images
Drop your JPG, PNG, or WEBP files. Add up to 2 images on the free plan if you want to compress a whole batch (up to 10 on Starter).
We Compress Them
Our system figures out the best way to shrink each image without wrecking the quality. Takes just seconds.

What actually happens when you compress an image
How image compression works and when it stops helping.
JPG vs. PNG vs. WebP — different compression, different tradeoffs
JPG uses lossy compression built for photos — small files, slight quality loss. PNG is lossless and supports transparency, but compresses far less, better for graphics and screenshots with flat colors. WebP does both lossy and lossless, usually beating JPG and PNG at the same quality for a smaller file.
What lossy compression actually does to your pixels
Lossy compression throws away image detail the human eye is less likely to notice — subtle color gradients and fine texture get simplified. At moderate settings this is invisible; push the quality too low and you'll start seeing blocky artifacts, especially around sharp edges and text.
Why the same quality % looks different on photos vs. graphics
Photos have gradual color transitions that hide compression artifacts well — a photo at 70% quality often still looks fine. Graphics, logos, and screenshots have sharp edges and flat color blocks, where the same compression level shows visible banding or blur around text and lines.
Resizing dimensions vs. compressing quality
These are two separate levers: resizing shrinks the pixel dimensions, so a 4000×3000 photo becomes 1200×900, while compression reduces file size at the same dimensions by simplifying detail. For the biggest size reduction, both together beat either one alone.
Compressing for web vs. for print
Web images only need to look sharp on a screen, so more aggressive compression and lower resolution work fine. Print needs more retained detail and higher resolution, around 300 DPI, so compress more conservatively if the image is headed for a printer.
Batch compression and consistent results
When you compress multiple images at once, each is processed independently at the same quality target — so a busy photo and a simple graphic in the same batch can end up at noticeably different file sizes, even though the compression setting applied to both was identical.
Common Questions
Quick answers on limits, privacy and results.
When You Need to Compress Images
Big image files are a pain. They take forever to upload, eat up storage space, and make websites crawl. If you've ever waited for a webpage to load because some huge photo is taking its sweet time, you know what I'm talking about.
That's where compression comes in. We squeeze the file size down - way down - without making your images look bad. A 10MB photo becomes 2MB. Still looks great, but now it loads fast and doesn't hog space.
Why File Size Actually Matters
Smaller files load faster on websites. Google likes fast websites, so compressed images help your SEO. They're easier to email - nobody wants to wait while a 50MB attachment uploads. They use less cloud storage. They're friendlier to people on mobile data plans. Basically, smaller is better for everyone involved.
Real Uses for This
Website owners compress images so pages load faster, and photographers shrink portfolios before uploading them to online galleries.
