Which plan should I choose?

1 min read · Last updated June 2026

SlashImage has three plans. Free is for trying it out, Growth is for a busy single site, and Unlimited is for high-volume sites or agencies. The difference that matters most is how many images you can optimize per month.

The plans

PlanPriceImages per monthBest for
Free$0100Trying SlashImage, or a small personal site.
Growth$4.99/month or $49/year5,000A single busy site.
Unlimited$8.99/month or $89/yearNo monthly limitHigh-volume sites and agencies; also unlocks sub-keys.

Growth and Unlimited are billed monthly or yearly. The yearly option is cheaper, working out to about two months free.

What counts toward the limit

Each image you optimize counts as one credit, and each thumbnail size WordPress makes from it counts as its own credit. The WebP and AVIF copies of each are included at no extra cost. Your allowance is shared across every site and key on your account. See How are my credits counted?.
