ThumbGen vs ThumbnailPop

ThumbGen creates YouTube thumbnails from a written prompt, with the option to add reference images. It is a web service, and its output is prepared for YouTube’s 16:9 aspect ratio. FAST produces 1K images, while PRO offers 2K and 4K resolutions. Users can upload as many as eight reference images; each uses one credit. The service also supports creating several variations in one batch. ThumbGen says most images take 10–30 seconds to generate, depending on complexity and resolution. FAST 1K costs 8 credits per image; PRO costs 30 credits at 2K or 55 at 4K. The free plan is free, billed $0 one-time, and includes 150 credits. Starter costs $9.99 a month and includes 1,000 credits monthly; Creator costs $24.99 a month and includes 2,700. Credits reset each billing cycle and unused credits do not roll over. Subscriptions can be canceled anytime, with access through the billing period; subscription payments and unused credits are nonrefundable unless the law requires otherwise. Google sign-in is available, and support and privacy requests go through a contact form.

ThumbnailPop is a web tool for generating video thumbnails from a prompt, a video restyle, or a pasted script. It is aimed at YouTube creators who want to make thumbnails without Photoshop or design skills, and also lists YouTube Shorts and Twitch. Styles include Auto, Bold, Cinematic, Realistic, UGC, and Cartoon, with niche categories such as Gaming, Business / Money, Tech & AI, Lifestyle / IRL, and Other. Templates cover Vlog, Gaming, Reaction, Tutorial, ASMR, and Podcast thumbnails. A brand kit can keep channel colors, fonts, and the creator’s face consistent across generated outputs. The site says variants appear side by side in about 20 seconds or less, but differs on whether each run creates four or five. Exports are optimized JPEGs at 1280×720, capped at 2 MB. The free option includes five signup generations, all niche templates, and 1280×720 export, with no card required. One-time packs cost $9 for 50 generations or $29 for 200, without a subscription.
