General FAQ
Are my images uploaded to your server?
No for core editor operations. Image processing is designed to run in your browser so your files remain on your device during normal usage.
What can image-toolkit do in general?
You can compress, resize, convert, crop, remove backgrounds manually, create collages, adjust colors and effects, extract palettes, and generate icon packs for web and mobile apps.
What does image-toolkit not do?
It is not a layer-heavy desktop replacement like Photoshop or Photopea, it does not provide cloud project collaboration, and it does not run AI-heavy generation pipelines.
Which image formats are currently supported?
You can work with common formats like JPG, PNG, WebP, AVIF, and BMP depending on the selected tool.
Do I need to install software?
No installation is required. image-toolkit is web-based and runs in modern browsers with JavaScript enabled.
Can I use image-toolkit for social media and app assets?
Yes. You can resize and crop for social formats and generate favicon, iOS image sets, Android drawable sets, and app icon packs.
Is image-toolkit free to use right now?
Yes. The tools are designed to be free, fast, and accessible for everyday image optimization and editing tasks.
Are there quality limits when exporting?
Quality depends on source image, selected format, and browser capabilities. For lossy formats (like JPEG/WebP), lower quality means smaller files but visible compression may appear.
How can I report bugs or security issues?
Use the Support and Security addresses on the Contact page (/contact). For security automation, the same security contact is listed in /.well-known/security.txt.

Privacy and data handling
Privacy is a core expectation for image workflows. image-toolkit is built around browser-first processing for common operations so users keep local control in normal usage.
- Core image editing and transformation operations are designed to run in the browser.
- Normal usage does not require uploading your private images to a remote processing queue.
- You keep control of exports on your own device.
- You should still avoid working with highly sensitive assets on shared/public computers.
