OctoSqueeze vs Kraken.io
Kraken.io is a long-standing optimisation API that sells you megabytes: every plan is a monthly quota of data processed.
OctoSqueeze sells images: a plan is a number of compressions a month, whatever each file weighs. Which is cheaper depends entirely on your average file size.

Work it out from your average file size
- •At 1 MB per image, Kraken's $9 tier (2 GB) covers about 2,000 images; OctoSqueeze Starter covers 5,000 for the same $9.
- •At 100 KB per image — icons, thumbnails, graphics — the same 2 GB covers about 20,000 images, far more than Starter.
Multiply your images a month by your average size and compare that against both price lists; neither unit is better in the abstract.
Both products make images smaller and neither published a fair head-to-head benchmark, so this page compares what you get and what it costs, not compression ratio. Run your own images through both before you commit.
Choose Kraken.io if
your images are small, you want HEIC or GIF input, or you would rather buy a data quota than a count.
Choose OctoSqueeze if
your images are photographs around a megabyte, you want the bill to be the same number every month, or you want unlimited compressions at a flat $49.
Neither, in the abstract. Below roughly 400 KB average Kraken's quota usually stretches further; above it a per-image plan usually does.
Every compression you send, including one that fails — that is how the free plan is kept from being abused. A file we refuse before doing any work, such as a format we cannot keep, is not counted.
