TinyPNG Pro costs ~$39/yr + API fees — and unlike a tool you buy once, that bill never stops. Over three years that's roughly $117 for software doing a job your own hardware could just as easily do.
Where the subscription actually goes
Subscription + per-image API fees at volume is the sticker price. It compounds: cancel and you typically lose access to your own history, and most plans ratchet the price up as you add usage, seats or storage — the bill rarely stays flat for long.
Shrinkray: the pay-once alternative
Shrinkray does the same core job for $19, once. Batch-compress a thousand photos locally — JPG, PNG, WebP, AVIF — no upload limits.

| Batch size | Unlimited | Limited per batch |

Pay for a few months of any subscription compressor and you've already spent more than Shrinkray costs — and you still won't own anything.
Is the subscription ever still worth it?
If you need TinyPNG Pro's specific ecosystem, integrations or managed infrastructure and that's genuinely load-bearing for you, the subscription earns its keep — that's a real trade-off, not a trick. Shrinkray is for everyone else: people paying every month for a job that runs fine on hardware they already own.
