Image Editing Toolkit
Compress, resize, crop, rotate, strip metadata, watermark, mosaic, and extract color palettes locally in the browser.
Compress, resize/crop/rotate, strip EXIF by re-saving, watermark, mosaic/blur, and extract palettes in the browser.
Files are not uploaded. Canvas re-export removes most original EXIF/metadata. Browser-unreadable formats such as HEIC may be limited.
This tool runs in your browser. Inputs stay local and are not sent to any server.
How to use this result
Image work is rarely a single action. A user may resize a screenshot, strip metadata, add a watermark, blur a private area, and copy colors for a post thumbnail in the same session.
The workspace uses browser image decoding and Canvas-style re-export for the supported operations. That keeps normal image processing local and avoids uploading private drafts to a server.
Canvas re-export removes most EXIF metadata, but browser support varies by source format and some metadata may behave differently across PNG, JPEG, WebP, and mobile photo formats.
Very large files can exhaust browser memory, especially on mobile. For archival originals, keep a separate backup before destructive edits such as cropping or heavy compression.
Examples
Privacy resize
Blog image prep
Sensitive area blur
Common questions
Q.Does this support HEIC?
Only if the browser can decode it. HEIC conversion may need a separate library or server flow later.
Q.Are uploaded images stored by ZHS?
No. The editing workflow is designed around browser-local processing and download from the client.
Q.Does metadata stripping guarantee complete privacy?
No. Re-export removes most common EXIF data, but you should still visually inspect images for visible addresses, names, account IDs, or screenshots of private content.
Data handling notice
Browser-local processing: the main calculation or conversion runs in your browser.
No server storage: except for UI preferences such as favorites, ZHS does not store your input files or text on the server.
Sensitive-data caution: even with local processing, avoid entering production secrets, national IDs, financial data, or raw customer data into public web tools.
