Image Compressor

Upload your image, set your desired quality level using the slider (80% is recommended), and click Compress. Your image is re-encoded at the selected quality directly in your browser — no uploads, no signup, no limits.

It depends on the quality setting. At 80% quality, file size is significantly reduced with virtually no visible difference. At 60% or lower, some compression artifacts may become noticeable, especially in gradients or fine details. We recommend 80% for the best balance of size and quality.

You can compress JPG, PNG, WebP, and GIF images. You can also choose the output format — keep the original format or convert to JPG, PNG, or WebP during compression.

Yes. Upload up to 50 images at once and compress them all in one click. Each image is processed individually at your chosen quality setting, and you can download them all as a single ZIP archive.

No. All compression happens in your browser using the Canvas API. Your images never leave your device. We never upload, store, or access your files.

80% is the sweet spot for most uses — significant file size reduction with no visible quality loss. For web use, 70% works well. For print or archival purposes, use 90% or higher.

Yes. GoToolify works on any device with a modern browser. The interface adapts to mobile screens, and since all processing happens locally, you get the same performance on your phone as on your desktop.

There is no fixed file size limit. Since everything runs in your browser, the practical limit depends on your device's available memory. Most devices can handle images up to 50 MB without issue.
