About Image Converter

Features

Convert

Convert between WEBP, PNG and JPEG

Compress

Compress images for the web

Resize

Edit

Rotate and flip. Apply filters (grayscale, sepia, etc.). Remove EXIF metadata for privacy.

Base64

Encode/decode Base64 data-URI

Batch & ZIP

Handle multiple images at once. Download all as ZIP.

Inspect

Analyze and extract hidden metadata (EXIF, GPS, IPTC, XMP, ICC)

What metadata is analyzed?

Digital images can contain large amounts of hidden information embedded by cameras, phones and editing software. The Inspect tab extracts and displays all metadata categories below.

EXIF

EXIF (Exchangeable Image File Format) is saved by digital cameras and phones. Contains camera model, shutter speed, aperture, ISO, focal length, white balance, flash info, date taken and orientation.

Example: Canon EOS R6 Mark II, f/2.8, 1/250s, ISO 400, 70mm

GPS

GPS metadata stores exact coordinates (latitude, longitude, altitude) where the image was taken. Can reveal where you live, work or travel. Displayed on an interactive map in the tool.

Privacy hint: Always remove GPS before sharing on social media.

IPTC

IPTC (International Press Telecommunications Council) is mainly used by photographers and news media. Contains photographer, copyright, caption, keywords, location and contact information.

XMP

XMP (Extensible Metadata Platform) is Adobe's metadata standard. Stores editing history, versioning, ratings and tags. Can reveal which software was used (Photoshop, Lightroom, etc.).

ICC

ICC profiles (International Color Consortium) describe the image's color space — e.g. sRGB, Adobe RGB or Display P3. Important for correct color rendering on screen and in print.

AI Detection

The tool searches for known AI generation traces in metadata — e.g. prompt text, model names (Stable Diffusion, Midjourney, DALL-E) and generation parameters. Detection is heuristic and based on metadata, not image analysis.

About image formats

WEBP

WEBP is a modern image format developed by Google. It offers both lossless and lossy compression, often 25-35% smaller file size than JPEG/PNG at the same quality. Supports transparency and animation.

Best for: Websites, photos, graphics with transparency

PNG

PNG (Portable Network Graphics) is a lossless format that preserves every pixel exactly. Supports full transparency (alpha channel). File size can be large for photographs.

Best for: Logos, icons, screenshots, graphics with transparency

JPEG

JPEG is the most widely used photographic format. It uses lossy compression resulting in small file sizes but may show artifacts at high compression. Does not support transparency.

Best for: Photographs, images without transparency

Comparison

Format	Transparency	Lossless	File size
WEBP	✓	✓/✗	Smallest
PNG	✓	✓	Largest
JPEG	✗	✗	Small

Privacy

All images are processed locally in your browser. Nothing is sent to any server (except if you enter a URL to fetch an image).

What happens locally

All image processing
Format conversion
Compression
Resizing
Filters and editing
Base64 encoding
Metadata analysis (EXIF, GPS, IPTC, XMP, ICC)
Metadata removal via canvas re-encoding

What may be sent

URLs you enter for fetching (via proxy)
Map tiles loaded from OpenStreetMap if GPS coordinates exist (Inspect tab)

Frequently Asked Questions

Are my images uploaded to a server?

No, all processing happens locally in your browser. Your images never leave your computer.

Which formats are supported?

WEBP, PNG and JPEG for conversion. Most browsers also support AVIF and GIF for viewing.

What is the difference between WEBP, PNG and JPEG?

WEBP often gives the smallest file size with good quality. PNG is lossless and supports transparency. JPEG is best for photographs but lacks transparency.

What is EXIF data?

EXIF is metadata saved by cameras - such as date, camera settings and sometimes GPS location. Removing this protects your privacy.

What is Base64 used for?

Base64 encodes binary data as text, useful for embedding images directly in CSS or HTML without separate files.

Does the tool work offline?

Yes, after the first load the tool works completely offline.

How do I analyze metadata in an image?

Go to the Inspect tab, upload an image and the tool automatically extracts all available metadata — EXIF, GPS, IPTC, XMP, ICC profiles and more.

Does my image contain GPS coordinates?

Upload the image in the Inspect tab. If GPS data exists, a warning is shown and coordinates can be viewed in the GPS section. You can remove metadata by downloading a clean copy.

Can you tell if an image is AI-generated?

The tool searches for known AI generation traces in metadata (prompt text, model names, etc.). Detection is heuristic — possible traces are shown but it is not a definitive classification.

How do I remove metadata from an image?

Analyze the image first, then click »Download clean image (metadata removed)«. The image is re-encoded via canvas which strips all embedded metadata.

Does it work with HEIC and AVIF images?

Basic support exists but metadata extraction may be limited for these formats. JPEG, PNG and WebP have full support.

Is it safe to analyze images online?

Yes. All analysis happens locally in your browser — no image is uploaded to any server. Your images never leave your computer.

Technology

The tool uses Canvas API for image manipulation, JSZip for ZIP files and modern browser APIs for maximum performance.

Browser APIs
