Will this compress as well as TinyPNG?

Usually close on photographs, and usually not on flat-colour PNGs, where TinyPNG's quantizer has a decade of tuning behind it. What you get instead is no 20-per-batch cap, no 5 MB ceiling and no copy of your image on someone's server.

Image Compressor: what you'd pay elsewhere

AltFTool's Image Compressor re-encodes images in the browser with no batch or file-size cap. TinyPNG's Web Pro is US$3.25/month billed annually, and its free web tool stops at 20 compressions per batch and 5 MB per image. Kraken.io starts at US$5/month (US$50/year) with a free web interface capped at 1 MB per image.

Kraken.io: Paid plans are monthly data quotas — 500 MB (Micro) to 60 GB (Enterprise) — with overage billed at US$5/GB down to US$1/GB.

Sources (each opens in a new tab): TinyPNG — tinypng.com/, tinify.com/pricing/web, tinify.com/pricing/api, tinify.com/terms · Kraken.io — kraken.io/plans, kraken.io/web-interface, kraken.io/docs, kraken.io/, kraken.io/privacy. Software pricing drifts. If a figure here disagrees with the vendor's page, trust theirs.

What each free tier actually allows

Most of these products have a free plan, and whether you need to pay at all depends entirely on where its ceiling sits. Here is each one in the vendor's own terms.

TinyPNG (opens in a new tab)

Free web tool: max 20 compressions per batch ("Max 20 compressions" on the Web Free plan)
Free web tool: 5 MB maximum per image (paid Web Pro raises this to 75 MB, Web Ultra to 150 MB)
Free web tool: max 3 format conversions per session (unlimited only on Web Ultra)
Free web tool shows ads; "Ad free" is listed only under the paid Web Pro and Web Ultra plans
Developer API: first 500 compressions each month are free, then $0.009 per compression for 501-10,000/month and $0.002 each above 10,000/month
Files are uploaded to Tinify servers: "Images uploaded to the Service are temporarily stored, optimized and deleted within 48 hours." (Terms of Service)

Kraken.io (opens in a new tab)

Free account comes with a 100 MB testing quota, no credit card required
The free Web Interface caps each image at 1 MB; the PRO interface raises this to 32 MB
The free Web Interface allows up to 20 files per batch
Image resizing and image conversion are PRO-only — the free interface optimises only
Optimised images are available for download for 12 hours on the free Web Interface; Kraken's API docs state optimised images stay on their servers "for one hour only". PRO users keep files in Kraken.io Cloud Storage
Paid plans are monthly data quotas — 500 MB (Micro) to 60 GB (Enterprise) — with overage billed at $5/GB down to $1/GB depending on plan

What the paid tools still do better

Plenty of people should keep paying for these, and these are the reasons why.

TinyPNG

The compression engine is genuinely excellent — a decade of tuning on lossy palette quantization for PNG plus modern WebP/AVIF encoding usually beats a generic encoder preset at the same perceived quality.
It is a real pipeline product, not just a web page: a documented API with 500 free compressions a month, official WordPress and Photoshop plugins, and an Image CDN, so compression can be automated inside a build or CMS instead of done by hand.
Because compression runs on their servers, a 150 MB image or a large batch processes at full speed on any device — a low-powered laptop or phone never becomes the bottleneck.

Kraken.io

The compression engine is the product, and it is a strong one: lossless and intelligent lossy modes tuned per format across JPG, PNG, WebP (incl. animated), GIF, SVG, AVIF, HEIC and PDF, with a detailed savings report.
It is built for automation, not one-off use: a full REST API, WordPress plugin, Magento extension, and direct delivery of optimised files to S3, Azure, Cloud Files or SoftLayer. A browser-only tool cannot optimise an entire site's image pipeline on a schedule.
Server-side processing means very large batches and heavy formats do not depend on the user's device or browser memory, and results are consistent regardless of the machine used.
Kraken.io Cloud Storage keeps optimised assets retrievable for paid users, which suits agencies re-downloading assets long after the job ran.

And what the free Image Compressor does not do

This is a browser re-encode, not Tinify's tuned palette quantizer. On flat-colour PNGs and logos, TinyPNG will usually produce a smaller file at the same perceived quality.
No API, no WordPress or Photoshop plugin, no S3 delivery and no image CDN — nothing here fits into a build pipeline.
No target-size mode: you set quality, not an output file size.

What the free Image Compressor does

Compresses PNG, JPG and WebP with no per-batch or per-session counter
No 5 MB or 1 MB per-file ceiling — the limit is your device's memory
Images are re-encoded locally and never uploaded to us

Open Image Compressor — it is the real tool, not a demo
