PixForge is a production-grade image processing API: one endpoint that resizes, converts, compresses, and watermarks any image, with the caching, rate limiting, and uptime you'd otherwise have to build yourself. It runs on libvips (via sharp), so it's fast and memory-efficient even on large images. This free tool is the same engine, so the output you see here is identical to what your code receives.

How it works

Give PixForge a public image URL (or base64 from your own code) plus the transforms you want. It applies them in a predictable pipeline — orient, resize, recolor, watermark — then encodes to your chosen format and caches the result on a CDN. This tool wraps a single GET /image request, so everything here is available from your own code.

What it can do

Resize and crop with cover, contain, fill, inside, or outside fit
Convert between WebP, AVIF, JPEG, and PNG with quality control
Compress for the web and strip EXIF metadata by default
Grayscale, tint, blur, rotate, and flip
Overlay a text or image watermark with adjustable position and opacity

Use cases

Generate responsive thumbnails and WebP/AVIF variants for the web
Shrink user uploads before storage to cut bandwidth and cost
Watermark product or stock images automatically
Normalize and re-encode images coming out of AI image generators

FAQ

Is the image tool free?: Yes — free to use, no signup. The PixForge API behind it has a free tier of 50 transforms/month; paid plans start at $5/mo for 1,000 and scale to 60,000.
Which formats can it output?: WebP, AVIF, JPEG, and PNG. Omit format to keep the source format while still resizing/compressing.
Can I send my own image bytes?: Yes. POST /image accepts { "image": "<base64>" } in addition to a url.
Is EXIF/location data removed?: Yes — metadata is stripped by default. Pass stripMetadata=false to keep it.

API reference

Call it through RapidAPI. Base host: pixforge-image-processing.p.rapidapi.com. Send your key as X-RapidAPI-Key and the host as X-RapidAPI-Host.

GET POST/image

Transform an image from a URL (GET or POST) or base64 (POST). By default it 302-redirects to the cached result; add json=true to get a JSON { url } instead.

Param	Type	Description
urlrequired*	string	Public image URL. *Or send `image` (base64) in a POST body. Internal/private hosts are blocked.
width / heightopt	number	Target size in px (1–6000). `w`/`h` aliases on GET.
fitopt	string	`cover` (default), `contain`, `fill`, `inside`, `outside`.
formatopt	string	`webp`, `avif`, `jpeg`, `png`. Omit to keep source format.
qualityopt	number	1–100 (default 82).
grayscale / blur / tint / rotate / flip / flopopt	mixed	Recoloring and geometry options.
watermarkopt	object	POST only: `{ text \| imageUrl, gravity, opacity }`.
stripMetadataopt	boolean	Default `true`; set `false` to preserve EXIF.
jsonopt	boolean	`true` → `{ url, format, bytes }`; otherwise a 302 redirect.

Returns a 302 redirect to the optimized image on the CDN, or { url, cached, format, bytes } when json=true.
