These free browser-based image tools handle the most common image tasks without requiring any software installation. Everything runs locally in your browser — your images are never uploaded to a server.
Not sure which format to use? Here's a quick guide:
| Format | Best For | Transparency | Lossy? |
|---|---|---|---|
| JPG | Photographs, complex images | No | Yes |
| PNG | Graphics, text, illustrations | Yes | No |
| WebP | Web images (modern browsers) | Yes | Both |
JPG is the right default for photographs and camera images. It achieves small file sizes through lossy compression, which works well on natural scenes where subtle losses aren't visible.
PNG is the right choice for anything created digitally — logos, diagrams, screenshots, and graphics with text or sharp edges. It's lossless, so quality never degrades, and it supports a full transparency channel.
WebP is a modern format that improves on both JPG and PNG for web delivery: smaller files than JPG at equivalent quality, and smaller lossless files than PNG. All major browsers have supported it since 2020.
Do these tools upload my images anywhere?
No. All processing happens locally in your browser using the Canvas API and JavaScript. Your images never leave your device.
What's the largest image these tools can handle?
There's no hard file size limit, but very large images (above 20–30 MB) may be slow to process depending on your device's memory and CPU.
Can I use these tools on mobile?
Yes. All tools are designed to work on phones and tablets as well as desktop browsers.
Which format gives the smallest file size?
It depends on the image. For photographs, lossy WebP typically produces the smallest files. For graphics and icons, PNG or lossless WebP are better choices. Use the compression tools to compare sizes directly.
