# ImgHub > ImgHub is a free online image toolkit by the independent developer Rollkey. It offers 14 browser-based tools for drawing and photo editing, image compression, AI image enhancement, OCR text extraction, watermarks, image splitting, screenshots and meme or subtitle image creation. No account or installation is needed, and most tools process images locally in the browser without uploading them. Every page is available in Simplified Chinese, English, Japanese. URLs follow https://imghub.oumashu.top/{lang}/tools/{tool}/ with lang = zh, en, ja. ## Tools - [Subtitle Screenshot Generator](https://imghub.oumashu.top/en/tools/subtitle-generator/): Turn your own lines into subtitle screenshots, quote graphics and caption memes. Choose a built-in speech background or upload an image, use single-language or bilingual text, and adjust the font, size and color. The preview updates as you edit, and the finished screenshot downloads as PNG. - [Wiggle Studio](https://imghub.oumashu.top/en/tools/wiggle-studio/): Turn part of a still photo into springy motion. Paint the area that should move, select a motion preset and adjust intensity and speed, or drag the soft region directly. Record the motion you see and export a looping GIF, or WebM and MP4 when your browser supports recording them. It works well for animated reactions and playful photo effects. - [Online Drawing & Image Editor](https://imghub.oumashu.top/en/tools/online-drawing/): Draw and edit photos in one browser workspace. Start with a blank canvas or a local image, then add brush strokes, text and shapes. Layers, cropping and color adjustments help you finish social graphics, simple illustrations and annotated screenshots without installing an editor. Editing takes place in your browser. - [MBTI Personality Grid Maker](https://imghub.oumashu.top/en/tools/mbti-grid/): Create an MBTI personality grid by pairing selected types with images. Start with the built-in papercraft character examples or replace them with your own pictures, adjust each crop and export a WebP. Use it for character comparisons, friend groups and MBTI memes. It does not test or automatically classify personality. - [DND Alignment Chart Maker](https://imghub.oumashu.top/en/tools/dnd-alignment/): Build a DND alignment chart with nine images, from Lawful Good to Chaotic Evil. Assign characters, friends or objects to each cell, adjust image scale and position, and optionally add descriptions or quotes. Preview the whole chart before downloading a single WebP comparison image. - [Pornhub Style Logo Maker](https://imghub.oumashu.top/en/tools/pornhub-style/): Make a Pornhub-style text logo with a black background, white lettering and an orange block. Customize two text segments, choose horizontal or stacked layout and adjust font size and spacing. The canvas updates as you edit and downloads as PNG, making it useful for text memes and stylized titles. - [Image Compressor](https://imghub.oumashu.top/en/tools/image-compress/): Balance image quality and file size with batch JPG, PNG and WebP compression. Set an encoder quality, choose a target in KB or limit the longest edge, then compare the result with your original. Automatic mode compares suitable formats and the source file to find a smaller output for web graphics, email attachments and upload limits. - [Image Enhancer](https://imghub.oumashu.top/en/tools/image-enhancer/): Enhance low-resolution and compressed images locally with Real-ESRGAN super-resolution. Choose original-size, 2× or 4× output, adjust strength, compare with a slider and inspect at 100% before exporting WebP. Automatic mode prefers local WebGPU and falls back to CPU. Images are never uploaded for processing. - [Image Splitter](https://imghub.oumashu.top/en/tools/meme-slicer/): Split an image into evenly sized rows and columns for meme sheets, nine-tile layouts or shorter pieces of a long image. Adjust the grid and inspect the boundaries before downloading a ZIP of PNG tiles. Each filename includes its row and column so you can organize the pieces in the original order. - [Add Watermark](https://imghub.oumashu.top/en/tools/watermark-adder/): Add a text or logo watermark to credit photos, portfolio images and product graphics before sharing. Adjust its size, position, angle and opacity, or tile it across the whole picture. Preview your changes and download PNG, JPG or WebP (the original format by default). Both the base image and watermark are processed in your browser. - [AI Watermark Remover](https://imghub.oumashu.top/en/tools/ai-watermark-remover/): Experimental whole-image autoencoder reconstruction and latent perturbation for GPT-image / Nano Banana images. Uses local WebGPU when available or CPU, without uploading images. Detail changes and invisible watermark removal remains unverified. Gemini visible sparkle restoration, local inpainting and metadata cleaning are also available. - [Online OCR](https://imghub.oumashu.top/en/tools/image-ocr/): PP-OCRv5 detects and reads text locally in your browser. Simplified and Traditional Chinese, English and Japanese can be mixed without language selection. Upload or paste, recognize the whole image or a region, inspect text boxes and confidence, then edit, copy or export TXT and boxes JSON. Long images use overlapping source-resolution tiles. Automatic mode prefers local WebGPU and retries on CPU when unavailable or unsuccessful. - [Video Thumbnail Downloader](https://imghub.oumashu.top/en/tools/video-thumbnail/): Find Bilibili and YouTube video thumbnails for reference, media notes or cover-layout research. Enter a full Bilibili URL, BV / AV ID or YouTube link, inspect the available cover and dimensions, then download WebP. YouTube offers several quality options, but the highest available resolution depends on the video. - [Full Page Screenshot](https://imghub.oumashu.top/en/tools/screenshot/): Capture your screen in the browser, or stitch a scrolling webpage into one long screenshot. Screen capture lets you pick a tab, window or whole screen. Full-page capture compares frames as you scroll and appends only new content, keeping sticky headers and fixed footers once. Frames are processed on your device, and you can select the area to keep before exporting. ## Language versions - [Simplified Chinese home](https://imghub.oumashu.top/zh/) - [English home](https://imghub.oumashu.top/en/) - [Japanese home](https://imghub.oumashu.top/ja/) ## About - [About ImgHub and its creator](https://imghub.oumashu.top/en/about/): Rollkey, contact wyh93829@gmail.com, https://x.com/Rollkey8 - [Privacy policy](https://imghub.oumashu.top/en/privacy/) - [Terms of service](https://imghub.oumashu.top/en/terms/)
