Compress Image
Compress JPG, PNG, and WEBP images to dramatically reduce file size while keeping them looking great. It's perfect for faster websites, smaller email attachments, and saving storage — and it all happens privately in your browser.
Overview
Our smart compression targets a file size you choose and preserves perceptual quality, so most images look identical to the original at a fraction of the weight. You see the exact before-and-after sizes and the percentage saved before you download, with no watermark added at any point.
What this tool does
The compressor analyzes your image and re-encodes it to hit a target file size while protecting the detail your eyes notice most. You set a maximum size and a quality level; the tool optimizes the image and reports the precise savings, keeping the original format intact.
Problems it solves
- Large images are slowing down a website and hurting Core Web Vitals.
- An email or upload form rejects files above a size limit.
- Cloud or device storage is filling up with bulky photos.
- You need many images small enough to load instantly on mobile.
Key benefits
- Reduce file size by up to 80%
- Smart compression preserves visual quality
- See exact before/after size savings live
- No watermarks, ever
Who it's for
How to use it
- 1
Upload your image
Drag in a JPG, PNG, or WEBP file. The tool reads the original size so you can see exactly how much you save.
- 2
Set your target size
Choose a maximum file size in megabytes. The compressor aims to land at or below it while keeping the image looking clean.
- 3
Fine-tune quality
Adjust the quality slider if you want to push the file smaller or hold onto a little extra detail.
- 4
Compress and download
Run the compression, check the before/after sizes and the percentage saved, then download your lighter image.
Example input and output
Example input
A 5.1 MB JPG product photo (3000×2000) for an online store.
Example output
A 480 KB JPG at the same resolution, about 90% smaller.
Targeting roughly 0.5 MB kept the photo visually identical on screen while making the product page load several times faster — a direct win for conversions and SEO.
JPG vs PNG vs WEBP
Not sure which format to pick? Here is how the three formats this tool supports stack up.
| Feature | JPG | PNG | WEBP |
|---|---|---|---|
| Compression | Lossy | Lossless | Lossy or lossless |
| Transparency | No | Yes (alpha) | Yes (alpha) |
| Animation | No | No | Yes |
| Typical file size | Small | Large | Smallest — about 25–35% under JPG |
| Best for | Photographs | Logos, graphics, screenshots | Almost anything on the web |
| Browser support | Universal | Universal | All modern browsers |
Short version: reach for WEBP on the web, PNG when you need transparency or crisp graphics, and JPG when you want a photo that opens everywhere.
Common use cases
Speed up your website
Compress hero images, thumbnails, and gallery photos to cut page weight and improve loading speed and search rankings.
Beat email attachment limits
Shrink images below common 10–25 MB caps so they send reliably without bouncing back.
Save storage space
Reduce the footprint of photo libraries on your phone, laptop, or cloud drive without deleting anything.
Optimize for mobile
Serve lighter images so visitors on slow or metered connections see your content load almost instantly.
Tips & best practices
Convert photos to WEBP before compressing
WEBP compresses photographs more efficiently than JPG or PNG, so converting first often lets you hit a smaller target size while keeping the image looking crisp.
Resize oversized images first
If an image is far larger than it will ever display, reduce its dimensions before compressing — you'll save far more than compression alone can.
Watch the before/after preview
Push the quality down until you just start to notice softness, then back off a step. That sweet spot gives the smallest file with no visible loss.
