Frequently Asked Questions
Answers to common questions about using Image Tools.
Are my images uploaded when I use these tools?
No. All image processing happens directly in your browser using JavaScript and WebAssembly. Your images are never uploaded to any server. When you close the page, the image data is released from memory.
Is this service free?
Yes. All tools on Image Tools are completely free to use. There are no hidden fees, no signup required, and no usage limits.
What image formats are supported?
Image Tools supports JPG, PNG, WebP, GIF, BMP, ICO, HEIC, and AVIF. Format support varies by tool — each tool page lists the specific formats it can handle.
Does compression reduce image quality?
Lossy compression (used for JPG and WebP) removes some data for smaller files. At moderate quality settings (75-85), most viewers cannot distinguish the compressed image from the original at normal viewing sizes. Lossless compression (PNG, WebP lossless) preserves all data.
Can I use these tools on my phone?
Yes. Image Tools works on any modern browser — desktop, tablet, or mobile. The tools are responsive and work on Android, iOS, Windows, macOS, and Linux.
What is the maximum file size?
File size limits depend on your device's available memory. Most modern devices can handle images up to 50MB. Very large images may take longer to process.
What is WebP?
WebP is a modern image format developed by Google that supports both lossy and lossless compression, transparency, and animation. It typically produces 25-35% smaller files than JPG at equivalent quality.
What is the difference between JPG and PNG?
JPG uses lossy compression and is best for photographs. PNG uses lossless compression and supports transparency, making it ideal for graphics, screenshots, and images with sharp edges.
How do I compress an image for my website?
Use the Image Compressor. Upload your image, choose a quality setting (75-85 is a good starting point for photographs), and download the compressed result. For web use, WebP format typically offers the best balance of quality and file size.
How do I convert HEIC to JPG?
Use the HEIC to JPG Converter. Upload your HEIC image (common on iPhones and iPads), and the tool will convert it to JPG format that is compatible with Windows, social media, and most image editors.
Do I need to create an account?
No. All tools are available without signing up. There is no account creation, no email collection, and no registration required.
Can I process multiple images at once?
Some tools support batch processing. Check the specific tool page for batch capabilities. The batch processing tools are listed in the Batch Tools collection.
