About Image Tools
Preparing images for websites, social media, documents, or email attachments is a repetitive task that most people handle in heavy desktop software or by uploading files to services that store your photos. These free browser-based image tools do the job faster and more privately: resize to exact pixel dimensions, compress to a target file size, or convert between JPG, PNG, and WebP formats - all without uploading anything to a server. The processing happens locally in your browser using the Canvas API, which means the tools work with any image including photos you would rather keep private. Download the processed result as a standard image file ready to use.

Frequently asked questions
- Is my image uploaded to a server when I use these tools?
- No. All image processing runs entirely in your browser using the Canvas API. Your images are never sent to any server. This makes the tools safe to use with personal, confidential, or proprietary images.
- What is the difference between JPG, PNG, and WebP?
- JPG (JPEG) uses lossy compression - it reduces file size by discarding some image data, which works well for photos but degrades quality at very high compression. PNG uses lossless compression - no data is lost, which is better for graphics with sharp edges, text, and transparency. WebP is a modern format developed by Google that offers better compression than both JPG and PNG at similar quality levels, making it ideal for web use.
- Will compressing an image reduce its quality?
- Compressing a JPG reduces quality because JPG compression is lossy. The Image Compressor lets you set a quality level (0-100%) so you can balance file size against quality. PNG compression is lossless - the file size decreases without any quality loss. Converting a PNG to WebP uses near-lossless compression that is usually visually indistinguishable from the original at a much smaller file size.
