Frequently Asked Questions (FAQ)
Everything happens directly in your browser using the built-in Canvas API. Your image is loaded locally, re-encoded at the chosen quality and/or size, and a new file is generated — no bytes ever leave your device.
No. The tool is entirely client-side (browser JavaScript). No network request is made to our servers or anywhere else with your file content.
Currently: JPG, PNG and WebP, both as input and output. You can compress in the original format or convert to any of the three (e.g. PNG to WebP for a smaller file).
The current limit is 15 MB per file. The tool processes one image at a time.
The current version uses the browser's built-in Canvas encoder, which re-encodes PNG without palette quantization. We are working on an upgraded compression engine specifically for PNG that will bring results closer to tools like TinyPNG.
It controls the trade-off between file size and visual quality for JPEG and WebP compression. A lower value means a smaller file but more visible loss of detail. This parameter has no effect on PNG, since the format is lossless by nature.
Yes. Enter your desired width and/or height in pixels. The "Keep proportions" option automatically calculates the other value so the image isn't distorted.
WebP supports both lossy and lossless compression and typically produces a significantly smaller file at comparable visual quality compared to PNG. For detailed images or ones with transparency, the result is usually much lighter than the original.
No. The tool is completely free and requires no account.
