Compress Videos for Sharing and Upload
Reduce video file sizes for faster uploads, smaller storage footprints, and easier sharing.
Compress Images Without Losing Quality
Reduce image file sizes for faster web loading and easier sharing while keeping them visually sharp.
Quick answer: Use the Compress tool through ToolRouter to compress images without losing quality directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolOversized images are one of the most common causes of slow websites and failed email attachments. A photo straight from a camera or a screenshot from a high-resolution display can be 5-10MB — far too large to attach to an email or load quickly on a webpage, yet reducing the size manually means finding a tool, uploading the file, waiting, and downloading the result.
The compress skill reduces image file size using modern compression algorithms that preserve visual quality. The output looks the same to the eye but loads faster and attaches without issue. JPEG, PNG, and WebP formats are all supported.
Web developers optimising page load times, marketing teams managing asset libraries, and anyone who emails or shares images regularly use this to cut file sizes without a degraded result.
How to compress images without losing quality with Claude, ChatGPT, Microsoft Copilot, and OpenClaw
Claude compresses images from a URL and reports on the size reduction achieved. You can ask follow-up questions — compare the compressed vs original size, request a more aggressive compression for a specific use case, or compress multiple images in one conversation.

Tips for Claude
- Provide the image URL directly — no upload required
- Ask Claude to compress a batch of images by listing several URLs
- Request a quality setting if you need to balance size vs sharpness for a specific use
ChatGPT compresses images and reports the results clearly — before and after sizes, compression ratio, and a download link for the optimised file. Useful when you need to process images for a specific context like a website or email campaign.

How to compress images without losing quality with Copilot
Once connected (see setup above), use the Compress tool:
- In Copilot Chat: "Compress this image URL: [url]"
- Copilot returns the compressed file URL and size reduction
- Ask: "Write Node.js code to call the compress skill for all images in this list"
- Integrate image compression into your build or deployment script
Example prompt for Copilot
Try this with Copilot using the Compress tool
Compress this image and write a TypeScript function that calls the compress skill for any image URL and returns the download URL: https://example.com/banner.jpg
Tips for Copilot
- Use compression as a build step to ensure all deployed images meet size budgets
- Ask Copilot to write the integration code and test it against a sample URL in one step
- Log original and compressed sizes to build a compression audit for your asset library
OpenClaw compresses images in bulk — process an entire asset library, run optimisation on a schedule as new images are added, and maintain a compressed copy alongside originals without touching each file manually.
