Do I need an account for the free plan?
No. Shrinkly opens straight into the tool: no sign-up, no card, nothing to remember. The free allowance is counted for your session and needs no account behind it.
What happens when a session’s allowance is spent?
Shrinkly stops starting new compressions once the compression count is reached, and new conversions once the conversion count is reached. The two are counted separately: Plus lifts the compression count, Studio lifts the conversion count as well, and the counts in force for this visit are listed under “What your plan allows right now” above.
Which formats can I bring?
PNG, JPEG, WebP and AVIF — the four that cover most of the web. Any mix of them can go through in the same session.
What does Shrinkly send to its backend?
The kind of work that finished and the size of the image in bytes, so the ceiling and the session count can be checked. The compression itself runs in your browser.
Why does the free plan carry an ad?
A free session needs no account and no card, and the ad beside the tool pays for it. Both paid plans turn the ad off, and Shrinkly answers with whatever is in force for your plan in the section above.
