Free social media image tools
Image resizers for platforms, thumbnail generators, profile pic tools, and post template builders.
Eight makers that each render to an HTML canvas at the platform's own pixel dimensions and hand the result back as a file, with no watermark burned into the output and no account behind the download button. YT Thumbnail Maker composes at 1280 by 720, the size YouTube serves, with heavy display faces such as Impact and Arial Black, outline and shadow controls, an A/B view for comparing two ideas and a mobile preview that shrinks the frame to roughly the width it gets in a suggestion strip. IG Story Maker works at 1080 by 1920 with gradient and solid backgrounds, stickers and saved brand-kit colour sets; IG Post Maker works at 1080 by 1080, supports multi-slide carousels and applies photo filters before export. Profile Frame builds an 800 by 800 avatar with a ring overlay — cause rings, celebration and seasonal styles, or a custom colour pair — composited over the photo you load. Tweet Image Gen redraws a post as a 1200-pixel-wide card in light, dark, dim or midnight styling, handles single posts, replies, quotes and threads, and lets you set the engagement numbers shown. LinkedIn Banner Maker defaults to 1584 by 396 and also carries presets for an X header at 1500 by 500, a Facebook cover at 820 by 312 and a YouTube channel banner at 2560 by 1440, plus an optional dashed guide marking the profile-photo circle that covers the lower left of a LinkedIn banner on desktop. Two tools here are not image editors. YT Thumbnail Download resolves a YouTube URL to a video ID and pulls the existing thumbnail files straight from Google's image host at each stored resolution, in single or batch mode — so that request goes to YouTube, not to a server here. Cover Letter Generator fills fixed letter templates from your details across five tones and four layouts; the wording is stored template text, not written on demand. Photos you drop into any of the makers are decoded locally, including HEIC files straight off an iPhone, which are converted in the tab before they ever reach a canvas.

How to choose the right tool
Pick by what has to change about the picture. If the composition is the work — type that has to read at thumbnail size, a ring around an avatar, a card that looks like a post — use the maker built for that exact canvas, because each one is already at the platform's dimensions and you never have to look a size up. YT Thumbnail Maker exists because a thumbnail is judged at postage-stamp scale and needs large type and hard contrast that no amount of resizing can add; check it in the mobile preview before you export. IG Story Maker and IG Post Maker differ by aspect ratio and by what surrounds it, with carousel slides and filters on the square post, and stickers and full-bleed gradients on the vertical story. LinkedIn Banner Maker is the one for any wide header, since its guide shows where a profile picture will sit on top of your text. Reach for Tweet Image Gen when you want a post as a picture for a slide or newsletter, and YT Thumbnail Download when the image you need already exists on somebody's video. If all you need is an existing image fitted to a platform size, that is the Social Image Resizer in the images hub, not a maker here.
Frequently asked questions
Are the exported images watermarked or size-limited?
No. Each maker draws to a canvas at full output resolution and exports from it directly, so the file you download is exactly the pixels you see, with no badge, no corner mark and no reduced resolution reserved for a paid tier. There is no account, no export quota and no per-day cap. The practical ceiling is your device: a 2560 by 1440 YouTube channel banner allocates real memory while it is being composed, and an older phone may stall on the largest sizes where a laptop will not notice.
Do my photos get uploaded when I use these makers?
The image you pick is read with the browser file API, decoded, drawn onto a canvas in this tab and exported from that same canvas. It is never sent anywhere. HEIC photos from an iPhone are the only extra step, and that conversion also happens locally before the picture reaches the canvas. The one tool that does touch the network is YT Thumbnail Download, which by definition fetches an image from Google's YouTube thumbnail host — there you are supplying a video URL rather than a file of your own.
Which canvas size does each maker use?
The platform's own. YT Thumbnail Maker is 1280 by 720, matching what YouTube serves rather than the 1920 by 1080 people often start from. IG Story Maker is 1080 by 1920 at 9:16, IG Post Maker 1080 by 1080. Profile Frame is 800 square, which is comfortably above what any platform displays an avatar at. Tweet Image Gen renders 1200 wide with a height that grows with the text. LinkedIn Banner Maker offers 1584 by 396 plus 1500 by 500, 820 by 312 and 2560 by 1440. Nothing is upscaled, so the export is native resolution throughout.
Can I use the tweet image generator to fake a post?
The tool renders whatever handle, text, timestamp and engagement counts you type, so a convincing-looking card is trivially easy to produce. That is what makes it useful for mockups, design comps, presentations and satire, and it is also why passing one off as a genuine screenshot is a bad idea. Platforms and readers increasingly treat unverified post screenshots as evidence of nothing. If a card is going anywhere public, label it as a mockup, and keep real quotes traceable to the original post.
Why does my LinkedIn banner look cropped after uploading?
LinkedIn renders the 1584 by 396 banner at different crops on desktop and mobile, and the profile photo sits over the lower-left corner on desktop layouts. Anything placed there disappears. The maker can draw a dashed guide over the preview marking that profile-photo circle plus the top and bottom safe-zone boundaries, and it has a desktop and mobile preview toggle, so keep text and logos inside the guides and check both views. The same caution applies to the other presets: an X header at 1500 by 500 is cropped differently in the app than on the web.
Does the cover letter generator write the letter for me?
It fills in templates. You supply your name, the role, the company, years of experience and a list of skills, then choose one of five tones — professional, enthusiastic, concise, confident or friendly — and one of four layouts. The tool substitutes your details into stored paragraphs written in that tone. No model runs and no text is generated on the fly, which means the output is predictable and private, but also that two people using the same tone and layout will produce similar letters. Edit the result before sending it.
