Image Encoder
Convert an image to a browser-ready Data URL/Base64 string. Runs fully on-device.
Image Decoder
Paste a complete Data URL or raw Base64, preview it, then retrieve the image. When the Data URL contains its MIME type, the original image format is preserved.
No decoded image yet.
Password Generator
Generate cryptographically-random passwords locally using crypto.getRandomValues(). Passwords and Save TXT details stay in your browser and are never uploaded by this app. Choose the active character rules below.

Hyperlink Maker
Create a rich hyperlink. The copy action writes both HTML and plain-text clipboard formats when the browser allows it.
No hyperlink generated yet.
Neutralize Text / Hyperlink Remover
Paste rich text below, then strip formatting and hyperlinks to keep the character content only. The Rich text input box can be resized vertically from its lower-right corner and scrolls automatically for long content.
PDF Compressor
Dedicated PDF size optimizer with a text-preserving first strategy. Advanced processing uses only free/open-source browser libraries loaded from a public CDN when required.
Smart Auto is recommended. It inspects sample pages for selectable text. Text-rich documents stay on structure-only rewriting; scanned/image-heavy documents may compare a text-preserving rebuild against balanced raster compression and keep the smaller useful result. Raster modes flatten page content to images. Digital signatures will no longer validate after any rewrite.
Compression Setup
Smart Auto preserves selectable text when text-rich pages are detected and only considers balanced raster compression for scanned/image-heavy PDFs.
Result
No PDF processed yet.
Compression Policy
Structure Only
Rewrites PDF objects with object streams. Best first choice for text/vector PDFs because text stays selectable and pages are not rasterized.

Raster Modes
Render each page to JPEG and rebuild the PDF while preserving the original page dimensions. Best for scans or image-heavy PDFs; selectable text and vector detail are flattened.

The app never labels a larger result as a successful compression. Smart Auto keeps the original recommendation when no useful reduction is found. Password-protected/encrypted PDFs may not be processable in this browser-only prototype.
Comp-Conv File
Portable image conversion/compression plus PDF ↔ image workflows. The app itself can run directly from file://; advanced PDF/HEIC engines are requested from public open-source CDNs only when the selected operation needs them.
PDF compression now has its own dedicated PDF Compressor tab. This Comp-Conv tab focuses on image compression/conversion, Images → PDF, and PDF → Images.
Image Compressor & Converter
JPG, PNG, WEBP and browser-decodable GIF work locally in file:// mode. HEIC/HEIF uses the optional heic2any engine from a public CDN when needed.
Images to PDF
Combine supported images into one PDF. No localhost is required; the PDF writer and HEIC decoder are loaded on demand when needed.
PDF to Images
Render every PDF page to JPG, PNG or WEBP and package multi-page output as ZIP. Works from file:// and loads PDF.js + JSZip on demand.
Portable runtime policy
- PDF.js — Mozilla PDF renderer, Apache-2.0.
- pdf-lib — browser PDF writer, MIT.
- JSZip — ZIP packaging, MIT/GPL dual licensing.
- heic2any — HEIC/HEIF conversion, MIT.
No localhost is required. Open this HTML directly with Chrome/Edge using file://. The ONLINE/OFFLINE badge is informational only and never enables or disables features. When an advanced operation needs an external engine, this build requests only free/open-source browser libraries from public package CDNs; no paid API key is required. If loading fails, the operation reports the actual error without silently switching engines.
