Image Editor

Edit photos, marketing assets, and UI mockups with PolyImg’s browser-based image editor—color corrections, text overlays, and filters all happen locally for maximum privacy and speed, ideal for “online photo editor” searches, pitch decks, and social storytelling.

Capabilities

Everything you expect from a pro editor—right in the browser

Professional-grade adjustments

Tweak exposure, contrast, curves, HSL, vignette, and blur entirely in your browser with GPU-accelerated Canvas rendering.

Text & graphic overlays

Add headlines, stickers, callouts, or watermark layers with font controls, blend modes, and draggable positioning.

Client-side image editor

All edits run via WebAssembly, OffscreenCanvas, and CSS filters so confidential designs never leave your device.

WebAssembly filters replicate Lightroom/Photoshop-style adjustments, so browser previews match production exports.
Workflow

Three steps to polished images

  1. 1Upload or paste any image—JPG, PNG, WEBP, SVG, or HEIC—and PolyImg renders a live preview immediately.
  2. 2Apply adjustments, filters, overlays, and annotations using the toolkit on the right side of the editor.
  3. 3Export optimized assets in your preferred format or copy them directly into your CMS/design suite.
  • Batch-edit multiple assets by syncing adjustments across selections, then fine-tune each individually.
  • Save reusable adjustment presets and watermark templates to IndexedDB so teammates stay on brand.
Quality & privacy

Pixel-perfect results with zero trust trade-offs

Tone mapping, denoise, and sharpening filters are optimized for product photography, helping you hit ecommerce and editorial standards without bloating file sizes.

Because the online image editor never uploads files, NDA-protected campaigns, health imagery, or legal documents stay private from start to finish.
