Compress Image
Shrink PNG, JPEG, and WebP files — nothing leaves your browser.
Large image files slow down websites, fill up inboxes, and eat into storage quotas. This tool shrinks them using the browser's Canvas API — the same technique used by professional image editors — with no data ever leaving your device. You control the quality-to-size trade-off with a slider, and an optional resize step lets you cap the pixel dimensions at the same time. Batch processing means you can compress an entire folder's worth of photos in one go.
How to Use
- 1
Drop one or more PNG, JPEG, or WebP images onto the upload area, or click to browse.
- 2
Set the quality slider — higher means better quality and a larger file; lower produces a smaller file with more compression.
- 3
Optionally enter a maximum width or height to scale the image down proportionally at the same time.
- 4
Click "Download All" to save every compressed image at once, or download each one individually.
Frequently Asked Questions
How much smaller will my files be?
It depends on the image and your quality setting. JPEG and WebP at quality 80 typically achieve 40–70% smaller files with almost no visible difference. PNG compression is lossless, so savings are smaller but quality is fully preserved.
Will compressed images look worse?
At quality 75 or above, most images look identical at normal viewing distances. Below that, blocky artefacts may appear around fine details. Always check the output before sharing.
Can I resize and compress in one step?
Yes. Enter a max width or height and the image is scaled down proportionally as part of the same compression operation — no extra steps needed.
Is there a limit to how many images I can compress at once?
No. Everything runs in your browser, so there are no server quotas. Drop as many files as you need — processing queues them automatically.
