RelahConvert Image Tools is a Media Library extension that integrates 38 image tools under a single plugin. Click a tool button on any attachment, process the image on RelahConvert.com, and the result is sent back to your Media Library automatically.
Individual tools in this plugin’s toolkit — watermarking, compression, meme generation, passport photos — also exist as standalone plugins in the directory. What this plugin offers is the combination and round-trip workflow:
38 tools in one plugin instead of installing 10+ separate single-purpose plugins
35 of the 38 tools run entirely in the user’s browser using JavaScript and Canvas — no server roundtrip, no API calls, no third-party upload for those 35 tools
“Send to WordPress” — processed image is POSTed back to the Media Library via a token-authenticated REST endpoint, no manual download / re-upload
Signup is optional — the 38 tools work without an account. Signing in (Google or email) is only needed if the user wants to use Save to Account (stores processed files on Supabase Storage) or sync preferences across devices.
No API keys required — all third-party API calls (Remove.bg, ApiFlash) are proxied through RelahConvert
No image quotas, no paid tier, no watermark on output
The 38 tools
Create — Meme Generator, Passport Photo (170+ country sizes), Watermark, Round Corners, HTML to Image (screenshot a URL)
Layout — Image Splitter (grid), Merge Images, Crop, Rotate, Flip
Privacy / effects — Blur Face (local face detection), Pixelate, Grayscale
Format conversion — 20+ conversions: JPG, PNG, WebP, GIF, BMP, TIFF, SVG, HEIC, ICO in various combinations
Optimization — Compress, Resize, Resize to exact KB size
AI — Remove Background (uses Remove.bg API)
PDF — JPG to PDF, PNG to PDF, PDF to PNG (extract each page as an image)
Where Processing Happens
35 of the 38 tools run entirely in the user’s browser using JavaScript and the Canvas API. Your image never leaves the device for these tools:
compress, resize, resize-in-kb, crop, rotate, flip, grayscale, watermark, round-corners, image-to-ico, merge-images, image-splitter, pixelate, blur-face (face detection runs locally), meme-generator, and 20+ format conversions (JPG, PNG, WebP, GIF, BMP, TIFF, SVG, HEIC, PDF in both directions).
3 tools use external services because the work can’t be done in the browser:
Remove Background — sends your image to the Remove.bg API for AI processing
Passport Photo — uses the same Remove.bg API for its background-removal step
HTML to Image — takes a URL you type in (not one of your images) and uses the ApiFlash API to return a screenshot
Optional, only if the user signs in: Save to Account uploads the processed file to Supabase Storage so it can be re-downloaded later. Sign-in is not required to use any tool.
Seamless WordPress Integration
Click a tool button in the Media Library → image opens on RelahConvert.com with your image auto-loaded → process it → click “Send to WordPress” → processed image lands back in your Media Library. No manual download and re-upload.
How It Works
Go to your WordPress Media Library.
Click any RelahConvert action button on an image (Compress, Watermark, Resize, Remove BG, or More Tools).
The tool opens on RelahConvert.com with your image auto-loaded.
Process your image with one click.
Click “Send to WordPress” to add the processed image directly back to your Media Library.
Third-Party Services
This plugin loads the processing UI from RelahConvert.com. When you click a tool button in the Media Library, your browser opens RelahConvert.com with your image auto-loaded.
What happens there depends on which tool you choose:
Client-side tools (35 tools) — Processing runs in your browser via JavaScript and Canvas. No network roundtrip for the image.
Remove Background / Passport Photo — Your image is sent to the Remove.bg API (a third-party service) for AI background removal. Subject to Remove.bg Terms and Privacy.
HTML to Image — The URL you enter (not your images) is sent to the ApiFlash screenshot service. Subject to ApiFlash Terms and Privacy.
Meme Generator — Fetches the public meme template catalog from the Imgflip API (no image upload).
Save to Account (optional) — Only if the user signs in with Google or email. Files are stored on Supabase Storage. Supabase Terms and Privacy.
Send to WordPress — Sends the processed image from your browser back to your WordPress site via a secure REST API endpoint using a short-lived token.
By using this plugin, you agree to RelahConvert’s Terms of Service and Privacy Policy, and to the terms of any third-party service you choose to use through it.
CORS Configuration
On activation, this plugin adds a CORS header to your wp-content/uploads/.htaccess file to allow RelahConvert.com to load your images for processing:
Header set Access-Control-Allow-Origin "https://relahconvert.com"
This rule is automatically removed when the plugin is deactivated.
