Privacy and Client-Side Security

Privacy Guarantee: All compression and format conversion occurs locally inside your browser. Your files and data are never transmitted, stored, or recorded on remote servers.

Many online image compression tools require you to upload your photos to their cloud servers. This introduces privacy risks, especially for sensitive or personal images. TinyToolzz takes a different approach: every operation runs inside your browser using the HTML5 Canvas API.

Because all processing is local, there is no upload wait time, no server dependency, and no risk of your images being stored or accessed by third parties. Your images exist only in your browser memory during the compression process and are discarded when you close the page or click Reset.

Frequently Asked Questions

How does browser-based image compression work?
When you select an image, the browser draws it onto an HTML5 Canvas element and re-encodes it at a lower quality level using the browser's native image encoder. The compressed result stays in your browser memory and is never sent to any server.
Are my uploaded images stored on a server?
No. All processing happens locally in your browser using the Canvas API. Your image files never leave your device and are not transmitted to any external server. When you close the page or click Reset, the image data is released from memory.
What image formats are supported?
This tool accepts JPEG, JPG, PNG, and WebP images as input. You can compress them in their original format or convert between formats — for example, converting a PNG to WebP for much smaller file sizes while preserving transparency.
Is there a file size or usage limit?
The maximum file size per image is 50 MB, which is set to protect your browser from running out of memory. There is no limit on how many images you can compress — the tool is completely free with no daily caps or sign-up requirements.
What quality setting gives the best results?
A quality setting of 80% is recommended. This typically reduces file size by 60-80% while keeping visual differences imperceptible to the human eye. Settings below 60% may introduce visible blockiness or color banding, especially in photographs with smooth gradients.
Can I compress PNG images and keep transparency?
Yes. PNG compression keeps transparency and reduces file size by lowering color depth — the quality slider controls how many color levels per channel are kept. Lower quality shrinks the file further but can introduce visible banding in gradients, especially below 60%. At 100% the PNG is kept fully lossless. For photographic images, converting to WebP usually produces the smallest file while still preserving transparency.
