Supports JPG, PNG, WebP and AVIF
How it works
- 1
Upload your images
Drag and drop one or more JPG, PNG, WebP, or AVIF files into the box above — or click it to browse. Nothing is uploaded to a server; the files stay on your device.
- 2
Tune quality and format
Each image gets its own quality slider and output format (JPEG, WebP, PNG, or AVIF). The live before/after preview and file-size readout update as you adjust, so you can see exactly what you are trading.

Download the result
Save images one by one, or use "Download all" to grab every optimized file at once. File names keep your original name with the new extension.
Why use ImagePilot?
100% private
Compression runs in your browser using canvas and WebAssembly. Your photos never leave your device — there is no upload, no queue, and no server storing copies.
Visual quality control
A side-by-side preview shows the original and compressed image at every quality level, so you never have to guess how much compression is too much.
Modern formats
Export to WebP or AVIF to get dramatically smaller files than JPEG at the same visual quality — ideal for websites that care about Core Web Vitals.
No limits, no watermarks
Compress as many images as you want, as often as you want. There are no daily caps, accounts, or watermarks.
Frequently asked questions
How do I compress an image to a specific file size?
Upload the image, then lower the quality slider and watch the size readout next to the preview. Because the result updates live, you can stop exactly when the file drops under your target — for example 100KB for a form upload or 2MB for a listing photo. Switching the output format to WebP or AVIF usually gets you under the target at a visibly higher quality.
Does compressing an image reduce its quality?
Lossy compression removes some detail, but at 70–85% quality the difference is usually invisible at normal viewing sizes. You are in control: the before/after preview shows exactly what the compressed version looks like before you download it. PNG output is lossless — pixels are preserved exactly.
Are my photos uploaded to your server?
No. ImagePilot is a client-side tool: the compression code runs inside your browser and your files never leave your device. You can even load the page, disconnect from the internet, and keep compressing.
Which format should I choose — JPEG, WebP, PNG, or AVIF?
Use JPEG for maximum compatibility, WebP for websites (roughly 30% smaller than JPEG), AVIF for the smallest possible files in modern browsers, and PNG when you need transparency or pixel-perfect graphics such as logos and screenshots.
Is there a limit on file size or number of images?
There is no fixed limit — processing happens on your own device, so capacity depends on your browser and memory. Batches of dozens of typical photos work fine.
