What You Can Do
One editor. Five ways to create. Edit existing thumbnails, design from scratch, generate with AI, make YouTube thumbnails, or create for any platform.
Start here
Create a new thumbnail, improve an existing one, or generate a concept with AI.
Start from a description or upload your own image, add readable text, and export a 16:9 thumbnail in HD, 2K, or 4K. The workflow is built around one small image that has to stay clear across the YouTube feed.
Describe the scene you want, optionally add reference images, and generate visual starting points for a YouTube thumbnail. Refine the result, add your text, and export in HD, 2K, or 4K.
Your thumbnail is almost right but something's off. Upload it, make targeted fixes to text, backgrounds, or faces, and export in minutes.
Your thumbnail is almost perfect but something's off. Upload it, make targeted fixes, and export without starting from scratch.
Already have a great photo or screenshot? Turn it into a professional YouTube thumbnail by adding text, removing backgrounds, adjusting colors, and cropping to HD. No need to start from scratch when your existing images work perfectly.
You should not need to install two gigabytes of software to fix one image. Open a tab, upload your thumbnail, make the edit, export in HD. Works the same on your desktop, your laptop, and whatever computer you happen to be sitting at.
Plan and improve
Test how a thumbnail reads, generate short headline ideas, and plan stronger concepts.
Upload up to three thumbnail versions and see them in seven YouTube layouts before you publish. Check mobile, desktop, search, suggested videos, light mode, and dark mode without creating an account.
Stuck on what to write on your thumbnail? Enter your video topic and get eight short options you can copy immediately. No signup, no long prompt, and no credit card.
"Cool gaming thumbnail" gives an AI nothing to work with, which is why most people's first generated thumbnail looks like nothing. A good prompt names the subject, the emotion, the lighting, and the composition. Here is a library of prompts that work, and the formula behind them.
Staring at a blank canvas is the slowest way to design. Steal from what already works instead: proven layouts, emotion patterns, and color combinations by niche, each one a prompt away from becoming your next thumbnail.
A font that looks great on a poster can fall apart on a 200-pixel thumbnail. Here are the fonts that survive the shrink, and how to test yours before you upload.
Upload any thumbnail to extract its six dominant colors, copy exact HEX values, and see how every swatch behaves against YouTube light and dark surfaces. The analysis runs locally in your browser.
Enter registered impressions and views from impressions to calculate CTR, then model how many views the same impression count would produce at a target rate. Use it for diagnosis, not as a promise of future performance.
Make targeted fixes
Remove backgrounds, edit text, reuse an image, or turn a video into a thumbnail.
Your expression was perfect. So was the pile of laundry behind you. One click removes everything except you, hair and all, and puts a clean color or a generated scene in its place.
Some thumbnails need a specific font, in a specific spot, at a specific size, not an approximation from a prompt. Pick the font, drag it where you want it, resize by hand, and set the exact color yourself.
The classic thumbnail move: you, cut out cleanly, dropped onto a background that makes the video look bigger than your bedroom. The AI handles the edges, including hair, and puts you wherever the story needs you.
Start with a public YouTube URL or upload your own video. Review the available preview frames, capture the exact moment you want, and turn the video title, key moment, and transcript into a focused thumbnail brief.
You know exactly what you want the thumbnail to look like. Now just say it. Type a description and the AI builds it, no stock photos, no templates, no blank canvas.
You already wrote your video description. It tells the whole story, what the video is about, the hook, the value. Paste it in and the AI figures out what the thumbnail should look like.
Generate a scene or upload a thumbnail, choose the detected face, then add a source photo you have the right and consent to use. Review the result before exporting.
Upload a thumbnail and create a 2560x1440 PNG using high-quality Lanczos resizing. This increases pixel dimensions and can produce a cleaner 2K export, but it cannot recreate detail that is missing from a blurry source.
Study the composition, lighting, colour rhythm, and focal hierarchy of a reference, then rebuild those high-level choices around your own subject and story. The workflow explicitly avoids copying text, logos, faces, or distinctive branded elements.
Built for each platform
Create covers at the correct aspect ratio with platform-specific sizing and safe-zone guidance.
Instagram doesn't use one image size, it uses three: a square feed post, a taller 4:5 portrait post, and a full-screen 9:16 Reel or Story cover. Describe what you want once, pick the format, and get an image sized exactly right instead of guessing and getting cropped.
TikTok picks a random frame from your video as the default thumbnail unless you upload your own. Describe the thumbnail you want, generate it at TikTok's real 1080x1920 size, and upload it as your custom cover instead of leaving it to chance.
Built for the niche
Examples and workflows shaped around the visual language viewers already recognize.
Gaming feeds move fast and every thumbnail in them is screaming. A raw gameplay screenshot does not stand a chance. Describe your moment, whether it is Minecraft, Fortnite, or GTA, and get the neon, the explosion, and text that still reads at phone size.
Describe a Minecraft-style scene, upload a screenshot or a transparent render of your own skin, and build a clear 1280x720 thumbnail for your next video.
Create a bright, readable thumbnail for Doors, Adopt Me, Brookhaven, Rivals, or obby content. Start with a gameplay screenshot or describe a Roblox-style scene, then export it for YouTube.
GTA thumbnails need to match the energy of the game. Hot oranges, neon purples, supercars, explosions. If your thumbnail looks calm, nobody clicks. Make it feel like Los Santos.
Fortnite is one of the loudest-looking games ever made, so a dull thumbnail on Fortnite content reads as instantly skippable. Get the neon purples, the electric skies, and the Victory Royale energy without opening Photoshop.
Ranked clips, agent guides, clutch moments. Valorant thumbnails need sharp lines, high contrast, and the game's signature neon energy. Build yours in minutes.
Twitch auto-generates VOD thumbnails from random stream screenshots. Most of them look terrible. Custom thumbnails get your past content watched instead of ignored.
Reaction thumbnails live or die on the face. The shock, the wide eyes, the disbelief. Describe the expression you need and AI generates it in 30 seconds, no camera or photo shoot required.
Start with your video idea or an authorized gameplay screenshot, make the brawler and objective obvious, then add a short label that stays readable at feed size.
Nuke streaks, Warzone wins, zombie round records. COD thumbnails need gritty military energy, explosive action, and text that hits as hard as the gameplay. Make yours in minutes.
20 bombs, Predator pushes, clean squad wipes. Apex content needs thumbnails with real stakes and tactical energy, not a flat gameplay screenshot. Build yours in minutes.
Made for the format
Purpose-built starting points for recurring formats with their own artwork and branding needs.
Build a serious case-focused visual around one non-graphic clue: a redacted document, a location, a timeline, or an object connected to the story. Keep the artwork accurate and respectful to the people involved.
Build a clear thumbnail around the actual video format: a property tour, market update, neighbourhood guide, listing breakdown, or first-time buyer explanation.
Your episode took hours to record and edit. The artwork should take five minutes. Drop in the guest photo, the episode number, and your show branding, and get covers that look intentional instead of improvised.
Tech review thumbnails win on clarity, not chaos: the product, clean, centered, with just enough context to signal what's being reviewed. Describe the product and layout, and build one in minutes.
Finance thumbnails sell a concrete outcome: a number, a chart line, a lifestyle result. Vague "get rich" stock photos don't convert. Describe the specific outcome and build a thumbnail that shows it.
Vlog thumbnails succeed by feeling real, not staged. A genuine moment, a specific place, an honest expression. Describe the day or the scene, and build a thumbnail that still feels like you.
Course thumbnails succeed on instant clarity: what will I learn, and can I trust this teacher. Describe the topic and the tone, and build a thumbnail that looks credible from the first glance.
Practical guides
Get the dimensions right, learn the fundamentals, and compare the workflows that fit you.
Use a 16:9 canvas, choose one clear subject, keep any text short, and preview the result at phone size. This guide covers the practical choices that make a thumbnail easier to understand and test.
YouTube currently recommends a 3840x2160 thumbnail in a 16:9 ratio. Use the guide below to choose a sharp export, stay within the upload limit for your device, and avoid cropping surprises.
The channels you recognize instantly in your feed got there by repeating themselves: same colors, same layout, same font every time. You don't need a formal template system for that, just the same prompt formula and design choices each time you create a new thumbnail.
Canva is fine until you notice your thumbnail template on three other channels in your niche. Describe what you want instead and get an image nobody else has, without scrolling a template library at all.
Photoshop can do everything, which is exactly the problem: you need one image, not a certification. Skip the monthly subscription and the tutorial rabbit hole. Describe the thumbnail, generate it, add text, export.
