Image API vs TinyPNG, Squoosh & iLoveIMG

TinyPNG has a beautiful compressor and an API — but the API is key-gated and metered past its free monthly quota. Squoosh is Google's excellent in-browser optimizer with no API at all. iLoveIMG is a full web suite whose API is paid. The Forge Image API resizes, converts, compresses, and inspects images as free REST endpoints — no key, no per-image quota, no watermark — so you can drop it into a thumbnail pipeline or a CI image-normalization step.

Where Forge Image Wins

1. A free, key-free REST API

TinyPNG's API needs a key and caps the free tier; iLoveIMG's API is paid; Squoosh has no API at all. Forge Image is one curl with no account:

curl -X POST -F "file=@photo.png" \
  "https://forge-node.tail2b516d.ts.net/image/resize?width=800"

2. Format conversion across the common set

Convert between PNG, JPEG, WebP, GIF, BMP, and TIFF from a script — normalize an upload folder to WebP, or down-convert TIFFs to JPEG in a batch:

curl -X POST -F "file=@photo.png" \
  "https://forge-node.tail2b516d.ts.net/image/convert?format=webp" -o photo.webp

3. Compress without a monthly cap

Shrink file size for the web with POST /image/compress. It is rate-limited per IP for fairness, not metered against a monthly quota the way TinyPNG's free tier is — so a nightly batch job will not run out of credits mid-run.

4. Inspect before you process

POST /image/info returns dimensions, format, and size — useful as a guard step in a pipeline (skip files already under a threshold, or reject oversized uploads):

curl -X POST -F "file=@photo.png" \
  "https://forge-node.tail2b516d.ts.net/image/info"

When TinyPNG, Squoosh & iLoveIMG Are Still Fine

You want best-in-class compression quality. TinyPNG's perceptual compression and Squoosh's advanced codecs (MozJPEG, AVIF, OxiPNG) with a live quality slider produce excellent results for hand-tuned web assets.
You are optimizing one image by eye and want to see the before/after at different quality levels. Squoosh's visual comparison is built for that.
You need a full web suite — crop, rotate, watermark, PDF-to-image, bulk drag-and-drop UI. iLoveIMG bundles all of that.

Use Cases for Forge Image

Thumbnail pipelines. Resize uploads to a set of standard widths inside your upload handler or a cron job.
Format normalization. Convert a mixed folder of PNG/JPEG/TIFF to WebP for the web in one batch.
CI image checks. Reject oversized images or assert dimensions using the info endpoint.
Asset compression. Shrink a build's static images without a metered key in the secrets.
Avatar processing. Resize and convert user avatars on the fly.

FAQ

Is the Forge Image API really free?

Yes. No signup, no API key, no watermark. Rate-limited per IP. Details in the Image API docs.

Which formats are supported?

PNG, JPEG, WebP, GIF, BMP, and TIFF for conversion; resize and compress work across the raster formats. Files up to 10 MB.

How does compression compare to TinyPNG?

Forge compression is solid for general web use and has no monthly quota. For the very best perceptual compression on hand-tuned hero images, TinyPNG and Squoosh still lead — Forge wins on being free, key-free, and scriptable at volume.
