imagor is a self-hosted image server that turns one master photo into every size, crop, and format your site needs, generated on demand from a single URL. You describe the transformation in the address itself: a width and height, a smart crop, then a chain of filters for fill color, format, quality, and watermark. Requests stream through a pipeline built for parallel throughput, so a thumbnail costs milliseconds even when traffic peaks, and the same syntax your team may already know from thumbor works unchanged. Smart cropping keeps the important part of the frame, focal points pin the exact region that must survive, and detection plugins can blur faces automatically for privacy-sensitive publishing. Forty-plus filters cover the daily work of a media pipeline: text overlays with real fonts, image compositing with blend modes, rounded corners, redaction, sharpening, and per-channel color control. Output lands in modern formats including WebP, AVIF, and JPEG XL, with automatic format negotiation and a byte budget that squeezes quality until a file fits your limit. Processed results cache to filesystem, S3, or Google Cloud storage, signed URLs keep strangers from minting their own transformations, and a metadata endpoint returns BlurHash placeholders and average colors for lazy-loading galleries. A companion service adds video thumbnails, and an MCP template layer composes OG cards and product grids. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

Born at Brazilian media giant Globo.com, Thumbor answers imaging CDNs like Imgix and Cloudinary with an HTTP service where every image variant is just a URL. Ask for /300x200/smart/your-image.jpg and Thumbor fetches the original, crops and resizes on demand, and caches the result - one source file, unlimited renditions, no batch pre-generation pipeline. The "smart" in the URL is the signature feature: OpenCV-based face detection finds people in the frame and crops around them (no more thumbnails with severed heads), and when no faces exist, feature detection finds visually important corners and computes a weighted center of mass as the focal point. Beyond cropping, a chainable filter pipeline handles brightness, contrast, grayscale, blur, red-eye removal, rounded corners, rotation, watermarks, and format conversion with quality control - applied in order via URL segments. All common image formats work out of the box, and every layer is pluggable: loaders (HTTP, local, S3), storages and result storages (local, S3, Ceph, and community backends), engines, optimizers, filters, and even custom detectors, with the awesome-thumbor list cataloging the ecosystem. URL signing prevents abuse of your processing capacity. Integrations exist for Django, Rails, Node, WordPress, and most frameworks. MIT-licensed, battle- tested for over a decade.

Your product photos, tutorial clips, and user uploads can live on your own server with Openinary, a media platform that resizes, crops, converts, and delivers images and videos through simple URL parameters. Request a variant by editing the address: set width and height, fill-crop around a detected face, convert to AVIF or WebP, trim a video between two timestamps, or pull a thumbnail from the fifth second. Uploads land in S3-compatible storage you control, from AWS S3 and Cloudflare R2 to MinIO, and repeat requests are served from automatic caching instead of reprocessing the original. The admin dashboard keeps assets organized for browsing, searching, and reviewing what your applications actually serve. API keys gate programmatic uploads, so a web app, mobile backend, or build script can publish media without sharing storage credentials. Setup runs through a scaffolding command that writes the Compose file and environment, then walks you through creating the first admin account. Teams escaping per-transformation pricing keep the same URL workflow their code already uses and move the bill to a fixed server.

Immich Upload Optimizer shrinks every photo and video at the moment of upload, so a self-hosted Immich library stops growing faster than the disk beneath it. The proxy sits in front of your Immich server and receives uploads first, matching each file by extension against a task list you define in a YAML file. Images pass through JPEG-XL or Caesium command line tools for lossless optimization by default, preserving every pixel of the original capture. Owners who prefer smaller files can switch a task to lossy settings that cut image size dramatically at the same perceived quality. Video conversion ships disabled because lossless transcoding rarely wins space, and owners can enable HandBrake profiles for lossy conversion with strong savings. Tasks run in sequence with fallback: the first matching command that succeeds supplies the stored file, and an upload with no matching task is refused rather than stored unprocessed. Long conversions keep working in the background after a client disconnects, and the processed file still reaches Immich. Deployment adds one service to an existing Docker Compose stack, points clients at the proxy port, and removes the direct public port from the Immich server itself.

Fifty-plus image processing tools in a single Docker container, with no Redis, no Postgres, and no external dependencies: SnapOtter is a self-hosted image toolkit. The everyday operations are all here: resize, crop, compress, watermark, vectorize, meme generation, GIF creation, and format conversion spanning 55+ input formats (including 23 camera RAW formats) to 14 output formats. What sets it apart is the local AI layer: background removal, photo upscaling and restoration, object erasing, face blurring, OCR, and canvas expansion all run on locally hosted models, so no image ever leaves your server - a hard guarantee that cloud tools like remove.bg or Canva can't make. Optional NVIDIA GPU support accelerates those AI tasks substantially when hardware is available, but everything works on CPU. A built-in layer-based editor handles composition work directly in the browser, and screenshot beautification turns plain captures into polished visuals with backgrounds, shadows, and padding - useful for docs and marketing alike. Batch operations process unlimited images simultaneously, and the full REST API with OpenAPI documentation exposes every tool for pipelines and automations: thumbnail generation on upload, bulk RAW conversion, automated watermarking. For teams processing sensitive imagery or anyone tired of per-image SaaS pricing, SnapOtter replaces a stack of subscriptions with one private container.

Imagor Studio is a photo workspace where browsing a huge library and editing what you find happen in the same place, and the originals never get touched. The gallery scrolls virtually through thousands of images with no indexing wait, while drag-and-drop moves files between folders and multi-select handles bulk work. Open any image and the editor lets you stack layers: other images as overlays or watermarks, text layers you can style inline, and solid color layers with blend modes and opacity. Adjust color, apply effects, and crop with a live preview, then copy the generated transformation URL and use that rendition anywhere without exporting a file. A look you build once can be saved as a template in portable JSON and applied across the whole library, so a watermark, a resize, and a color grade become one reusable recipe. You can also start from a blank canvas at any dimensions and compose from scratch. Storage stays yours throughout: point it at a local folder, S3, MinIO, or Cloudflare R2 and manage the same library the same way.

Build your own image and video sharing site, with public galleries, private albums, and embeddable links, on a server you control. Uploads arrive by drag and drop, clipboard paste, image URL, camera, ShareX, or API, in AVIF, JPEG, PNG, GIF, WebP, BMP, MOV, MP4, and WebM, and chunked transfers handle large files. Lossless JPEG handling fixes orientation and can strip EXIF data. Duplicate detection catches repeat uploads. Tags are created on the fly with autocomplete, camera models become tags automatically, and albums nest into sub-albums with covers, privacy levels, and passwords. Categories, search, and explore views help visitors find things; a bulk importer brings in folders of existing media. Each file gets viewer, direct, thumbnail, and medium links plus HTML, Markdown, and BBCode snippets with one-click copy, and oEmbed lets other sites preview a link. Roles split admin, manager, and user duties, profiles can be private, and two-factor authentication protects accounts. Files sit on local disk or S3-compatible storage, optionally served through a CDN URL. A dashboard tracks usage, color palettes and custom CSS and JavaScript restyle the site, and a single-profile mode suits a personal portfolio. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

The social preview cards shown when links hit Twitter, LinkedIn, Slack, or Discord, generated on the fly: Oxigen is a small Go service for dynamic Open Graph images, no designer required per page. Instead of exporting static images per page, you compose a card once and drive it with parameters: title, author, website, logo, background image, and background dimming all arrive as URL query arguments, so your og:image meta tag simply points at the Oxigen endpoint with the page's own values substituted in. Every blog post, product page, and doc gets a branded, correctly sized preview generated on the fly. A built-in web UI covers interactive composition - tweak the text and imagery, watch the preview update, copy the resulting URL - while the same rendering path serves programmatic API use from static site generators, CMS templates, or build pipelines. Rendering is pure Go using the gg 2D graphics library, freetype fonts, and the imaging package, built on the kyoto framework by that project's author. Deployment is one stateless container on port 80 with no database and no external dependencies, so instances scale and restart freely.
