Is it safe? Are my images sent to any server?

No. The conversion happens 100% in your browser using the Canvas API. No byte of your images is sent to ToolboxHub servers or any third party — it even works offline after the page has loaded.

Is there a size or file count limit?

There is no limit imposed by the tool. The only practical limit is your device's RAM, since everything is processed locally. You can convert dozens of images in batch with no signup.

Can I convert multiple images at once (in batch)?

Yes. Drag several files or pick multiple in the file picker — they will all be displayed in the grid and converted together to the chosen format. Use the Download all button for bulk download.

What is the difference between PNG, JPEG, WEBP and AVIF?

PNG: lossless, preserves transparency, ideal for graphics and screenshots. JPEG: lossy, great for photos, no transparency. WEBP: modern compression that combines PNG-like quality with sizes close to JPEG. AVIF: the newest generation, offers the best compression with superior visual quality.

What does the quality control mean?

For lossy formats (JPEG, WEBP, AVIF), the quality control adjusts the compression level between 10% and 100%. Higher values preserve more detail but generate larger files; 90% is usually the best balance between visual quality and size.
