Metadata Remover
Free · Client SideRemove EXIF, GPS and author data before sharing.
How It Works
Losslessly strips all APP1-APP15 application markers (EXIF, IPTC, XMP, ICC profiles, GPS location coordinates) from the file stream. Keeps the raw compressed image entropy stream intact for 100% zero quality loss.
Settings & Parameters
| Control / Option | Range / Options | Description & Behavior |
|---|---|---|
| Processing Mode | Lossless Strip (Keeps original pixels, zeroes metadata) or Re-encode | Lossless is default. |
| Removed Tags Report | Displays list of stripped tags | Verifies GPS, camera serials, and dates that were purged. |
Colour Palette Extractor
Free · Client SideDominant colours as HEX, RGB and HSL.
How It Works
Applies median cut color quantization and k-means clustering across representative pixel samples. Isolates dominant hues, ranks them by frequency, and generates a harmonious design palette with HEX/RGB swatches.
Settings & Parameters
| Control / Option | Range / Options | Description & Behavior |
|---|---|---|
| Palette Size | 4 to 12 dominant colors | Number of color swatches extracted. |
| Sorting | By Dominance (Frequency) or Luminance (Light to Dark) | Organizes swatches. |

Favicon Generator
Free · Client SideConvert your logo to a multi-size .ico file.
How It Works

Zero-Upload Privacy Architecture
Unlike traditional online converters that upload your personal pictures to cloud storage buckets or third-party servers, Imgvx was architected from day one on a strict client-side guarantee:
100% In-Browser Execution
Your pictures are decoded directly inside your device's memory using HTML5 OffscreenCanvas, createImageBitmap, and Web Workers. No image file ever traverses the network.
No Third-Party CDNs
Every codec, stylesheet, and icon is served from this exact origin domain. Our Content Security Policy (CSP) blocks all external script injections, ensuring no third party can track your activity.
Offline Reliability
Once loaded, your browser caches the tool bundle. You can disconnect your Wi-Fi, airplane-mode your phone, or work in restricted environments with complete functionality.
No Telemetry or Tracking Cookies
We log zero personal identifiers, set no tracking cookies, and collect zero telemetry. What you edit remains exclusively your personal business.
Frequently Asked Questions
Clear answers to the most common questions regarding image editing, formats, performance, and security.
Is Imgvx completely free to use?
Yes, all 52 core tools on Imgvx are 100% free and unlimited. There is no account registration required, no credit card required, no subscription, and no watermark added to your exported images.
Do my images get uploaded to your servers?
No. All 52 free tools run entirely on your own device using client-side JavaScript, HTML5 Canvas, Web Workers, and WebAssembly. When you drop or select a file, it is decoded and processed locally in your browser memory. Your images never leave your computer or phone.
Can I use Imgvx offline without an internet connection?
Yes. Once you open a tool page, the client application bundle is cached in your browser. Because the processing logic is executed locally on your device CPU/GPU, you can edit, resize, crop, filter, and convert pictures without an active internet connection.
What is the maximum file size or resolution limit?
Because processing happens on your device, the file size is limited only by your browser memory. Imgvx comfortably handles high-resolution 50-megapixel camera RAW/JPEGs and 4K/8K graphics. For extreme scans above 40 megapixels, an automatic safety scaling guard ensures your browser tab does not freeze.
How does the DPI Converter change DPI without losing quality?
The DPI converter rewrites the metadata header tags (the JFIF density marker in JPEGs or the pHYs chunk in PNGs). It does not resample or recompress pixel data. Your original pixels remain 100% untouched while print shops and photo labs read the updated 300 DPI or 600 DPI print target.
Can I convert Apple iPhone HEIC photos on a Windows PC?
Yes. Our HEIC to JPG converter downloads a self-hosted WebAssembly port of the libheif decoder directly to your browser. You can convert any Apple HEIC/HEIF photo to standard JPEG on Windows, Linux, Android, or Mac without installing third-party desktop software.
Can I batch resize multiple photos at once?
Yes. The Bulk Image Resizer allows dropping dozens of photos or an entire desktop folder. It processes up to 4 images concurrently in browser memory and bundles the resized outputs into a single zip file for immediate download.
How do I extract text from a screenshot or scanned receipt?
Use our Image to Text (OCR) tool. It runs a compiled WebAssembly port of the Tesseract neural network optical character recognition engine directly inside a background Web Worker. You can copy the extracted text with one click, completely offline.
Can I remove private GPS location data from my photos?
Yes. Use the Metadata Remover tool. It performs a lossless strip of all EXIF, GPS coordinates, camera serial numbers, and personal timestamps from JPEG and PNG files without touching image quality or re-encoding pixels.
What image formats can I convert between?
Imgvx supports cross-conversion between PNG, JPEG, WebP, AVIF, HEIC, PDF, SVG, GIF, BMP, and ICO. You can adjust quality settings and transparent background options for each format.
Are images processed on Imgvx allowed for commercial use?
Yes. You own 100% of the copyright and commercial rights to any images you edit, convert, or create using Imgvx free tools. We claim no intellectual property rights or ownership.
Does Imgvx support dark mode?
Yes. Click the sun/moon icon in the top header to toggle between clean light mode and high-contrast OLED dark mode. Your theme preference is preserved automatically in your browser.
