Client-Side Engineering

About Image Text Editor

We built Image Text Editor to solve a frustrating everyday problem: modifying or replacing text in flat pictures without complex desktop software or privacy-invading cloud services.

Fast, Clean & 100% Private Text Replacement

Every day, millions of people need to update a price tag in a screenshot, correct a typo in a poster, translate a sign in a travel photo, or sanitize sensitive information in a document receipt. Until now, you had two bad options: expensive, bloated graphic suites with steep learning curves, or shady online websites that store your confidential photos on their servers.

100% Client-Side Privacy

Your files never touch any remote backend server. All image decoding, text recognition, pixel healing, and font rendering happen locally inside your browser sandbox.

Instant OCR Text Detection

Powered by optimized Tesseract.js engine, our editor detects paragraph lines, words, and exact bounding boxes in over 100 languages with millisecond response times.

Seamless Pixel Inpainting

Patented multi-mode background reconstruction analyzes surrounding textures, solid gradients, and edge geometry to cleanly erase original letters with zero ghosting.

Typography Auto-Matching

Automatic font size, color extraction, stroke borders, drop shadows, and slant angle detection ensure replacement text blends naturally into original artwork.

How It Works Under the Hood

Image Text Editor takes a radically different approach: 100% client-side execution. By running advanced OCR neural models and canvas inpainting algorithms directly inside your browser via WebAssembly, your images never leave your device.

01
Local Bitmap Ingestion

Your uploaded image is decoded directly onto an HTML5 OffscreenCanvas without any network payload or remote server latency.

02
Wasm OCR & Geometric Extraction

WebAssembly-compiled OCR analyzes letter contours, baseline angles, color median samples, and bounding regions across 100+ global languages.

03
Intelligent Mask Inpainting

High-precision glyph masking isolates text strokes while boundary-aware interpolation seamlessly restores the underlying photographic background.

04
Vector Layer Compositing

New editable text is dynamically composited with matching typographic properties, CSS styling, and lossless PNG/WebP export capabilities.

Everything You Need to Know

Everything you need to know about privacy, security, and technology.

Are my uploaded photos or documents stored on any server?

No. Absolutely never. All image processing, OCR recognition, background erasure, and text rendering are executed 100% locally in your web browser. You can even disconnect your internet after loading the page and the editor will continue to work perfectly.

Is Image Text Editor completely free to use?

Yes, it is 100% free with no hidden subscriptions, no usage credits, no watermarks, and no sign-up requirements. You can edit and export as many images as you need.

Which image formats are supported?

We support all modern image formats including PNG, JPG/JPEG, WebP, BMP, and SVG rasterization.

Can I replace text on complex photographic backgrounds?

Yes. The editor provides multiple inpainting algorithms (adaptive solid fill, directional gradient fitting, and smart blur) plus interactive color brush and eraser tools to handle both clean screenshot backgrounds and complex photo textures.

What languages can the editor detect and replace?

The OCR engine supports over 100 languages, including English, Simplified Chinese, Traditional Chinese, Japanese, Korean, Spanish, French, German, Russian, Portuguese, Italian, Turkish, Polish, Arabic, and Hindi.
