Free AI Image Upscalers
Which AI image upscalers a startup can enlarge and enhance product and marketing images with for free today, how many images or credits are free, the largest free output, whether a card is needed and what the first paid plan costs, read from each provider's own page.
Free allowances read on each provider's own pages, all checked on or after . AI upscalers change their free plans from time to time: confirm the terms on the provider's page before you rely on it.
AI image upscalers a startup can use for free today include VanceAI (10 free credits to try), Upscayl (Free and open source desktop app), Let's Enhance (10 free credits at sign-up), chaiNNer (Free and open source desktop app), and Upscale.media (3 free credits a month). Each of the 9 free plans below links to the provider's page that states it, with its main limit, the free output size, whether a card is needed and what the first paid plan costs.
Low-resolution product photos, old logos and screenshots look sharper at a larger size after an AI upscaler adds detail. Online upscalers give free credits or a small free allowance, and open-source upscalers run free on your own computer's GPU.
The headline rarely tells you how far it goes. Free credits are often given once, free images may carry a watermark or wait in a queue, and the largest upscale factors cost more credits. Each tool below shows what is free, its main limit, the free output size, whether a card is needed and what the first paid plan costs, quoted from the provider's own page with the date we read it.
Which tools we picked and the order they appear in are our editorial choices; the terms are the providers'. Some of these providers pay us a referral commission when someone signs up through our link: those links are labeled, and they play no part in which tools are listed or where.

How this comparison is built
The list covers AI image upscalers a founder can use for free today without applying to a program. The order and the "best for" notes are our editorial reading of each tool's terms. Every term comes from the tool's own pricing or help page on the date shown, never from a third-party list; follow each link for the full conditions. A cap on images or credits, a watermark or limited output resolution, commercial use kept for paid plans can matter more than the headline, so the comparison quotes them wherever the provider states them. Some of these tools pay StartupPerks a referral commission, and their links are labeled as referral links; that decides neither whether nor where a tool appears, and no tool pays for a placement on this page.
