Why I Built It Most people don’t need a full graphics suite. They just want to quickly:
Extend an image (AI outpainting) without weird borders
Upscale or unblur without making the picture look “AI smooth”
Remove background cleanly (not the soft-edge mess from traditional tools)
Fix awkward aspect ratios for social media
Compress large images without ruining quality
Do simple edits (crop/resize/filters/text) without learning complex software
But the existing tools are either:
too slow,
too complicated,
too expensive,
or too fragmented (one tool for background removal, another for upscaling, another for AI generation…).
I wanted one place that makes image tasks fast, predictable, and accessible.
What ImgExtender Does (Core Features) All tools work in-browser, no signup required. AI Image Tools
Extend Image (Outpainting) — expand canvas naturally using generative fill
AI Generate Image — text-to-image with clean, sharp output
Unblur Image — restore clarity using deep-learning deblurring
Upscale Image — 2×–8× enlargement with texture recovery
Editing Tools
Crop
Resize
Rotate & Flip
Add Text
Filters
Blur Background
Remove Background
Change Background
Utility Tools
Image Compressor
Image to PDF converter
It’s designed to be something even a non-technical person can use instantly.
Under the Hood (Technical Notes)
Outpainting uses a fine-tuned diffusion model that blends edge areas to avoid seam artifacts.
Unblur uses a multi-stage sharpness restoration pipeline (deconvolution + learned edge enhancement).
Upscaling uses a lightweight ESRGAN variant optimized for smoother detail recovery.
Background removal uses a segmentation model focusing heavily on hair & soft edges.
All processing is GPU-accelerated on the backend; front-end is minimal and optimized for speed.
I’m also working on client-side WASM acceleration for some tasks.
Who Uses It Today? From early usage logs and feedback:
AI artists fixing midjourney/dalle artifacts
Designers preparing images for clients
Etsy sellers enhancing product photos
Developers who need quick assets without opening Photoshop
Students / teachers improving slides or PDFs
Casual users cleaning up old photos
Roadmap
Batch processing
API access
A unified “smart enhance” mode
More style-aware AI generation
Client-side processing to reduce server load
If you use AI image tools often, I’d love to hear what your workflow looks like.
Feedback Wanted This is still early-stage. I would really appreciate feedback from the HN community on:
What feels slow or confusing
Which features matter the most
What is missing for real professional use
Whether you'd want self-hosting or local models
Your typical image-edit workflow
