Image Tools
Free, browser-based image tools to compress, resize, crop, convert and clean up photos and graphics without installing software or signing up. Your pictures are loaded into the page and processed on your own device, so they are never uploaded to a server.
Whether you are shrinking a screenshot to fit an upload limit, converting an AVIF to PNG, or stripping location data before sharing, the work happens entirely in the tab in front of you.

Base64 to Image Converter
Decode a Base64 string or data URL back into a viewable image and download it as PNG, JPG, WebP or GIF. Runs in your browser.
Try freeGIF Maker
Turn multiple images into an animated GIF with custom frame delay.
Try freeImage Metadata Viewer
View file info, dimensions, aspect ratio, and basic EXIF data from any image.
Try freeImage Vectorizer
Convert PNG, JPG, WebP, GIF or BMP images to scalable SVG vector format directly in your browser.

The two most frequent image jobs are making a file smaller and changing its dimensions. The image compressor reduces file size by re-encoding the picture at a chosen quality, which is ideal for hitting an email or upload limit without an obvious drop in clarity. The image resizer changes the pixel dimensions - set an exact width and height or scale by percentage - and for very large batches the backend image resizer handles heavier processing. The two pair well: resize first to the dimensions you actually need, then compress to trim the remaining bytes.
Convert between image formats
Format mismatches are a constant nuisance. The image format converter moves between PNG, JPG, WebP and other common types, while dedicated tools handle the trickier cases: image to AVIF for modern high-compression delivery, SVG to PNG when you need a raster from vector artwork, and Base64 to image plus image to Base64 for embedding pictures directly in CSS, HTML or JSON. The image vectorizer traces a bitmap into scalable vector paths.
Edit, crop and transform
Beyond size and format, the image cropper trims to a selection or fixed aspect ratio, and the flip and rotate tool fixes orientation in one click. For finishing touches, the image watermark tool overlays text or a logo, the blur and pixelate tool hides faces or sensitive details, and the image color picker samples exact hex values from any pixel. Need a stand-in graphic? The placeholder image generator produces sized dummy images for mockups.
Inspect and clean metadata
Photos carry hidden data. The image metadata viewer reveals EXIF fields such as camera model, timestamp and GPS coordinates, and the strip EXIF tool removes that metadata before you publish or share a picture - an easy privacy win that most online editors skip. For developers and designers, the favicon generator produces the icon set a website needs, and the image to ASCII tool turns a picture into text art.
Why in-browser image editing keeps your photos private
Images can be deeply personal - a passport scan, a child's photo, a product shot under embargo, a screenshot of private data. Most online image editors upload your file to a server to do the work, which means a copy of that picture now lives on someone else's machine. These tools use the browser canvas and codec APIs to read and rewrite images locally, so the original never leaves your device and is discarded the moment you close the tab.
- No upload - the file is read into the page, not sent anywhere.
- No signup or watermark - download clean output for free.
- Privacy-first by design - strip EXIF and GPS data before sharing.
- Composable - resize, then compress, then convert without re-uploading.
Frequently Asked Questions
Are my images uploaded when I use these tools?
No. Each image tool loads your file into the browser and processes it on your device using the canvas and built-in codec APIs. The picture is never sent to a ZeroUtil server, and it is discarded when you close or reload the tab, which is why the tools also work without an account.
What is the difference between compressing and resizing an image?
Resizing changes the pixel dimensions (for example 4000x3000 down to 1280x960), while compressing keeps the dimensions but re-encodes the image at a lower quality to reduce file size. For the smallest possible file you usually resize to the dimensions you actually need first, then compress to trim the remaining bytes.
How do I remove location data from a photo before sharing it?
Use the strip EXIF tool to remove embedded metadata, including GPS coordinates, camera model and timestamps, then download the cleaned copy. You can confirm what a photo currently exposes by opening it in the image metadata viewer first, which lists every EXIF field present.
Which format should I convert my images to?
Use JPG for photographs where small size matters, PNG when you need transparency or sharp edges, and WebP or AVIF for the best compression on the modern web. The image format converter handles the common cases, and there are dedicated tools for AVIF and SVG to PNG when you need them.
Can I edit images on my phone with these tools?
Yes. Because everything runs in the browser, the tools work on mobile browsers as well as desktop, with no app to install. Very large images can be limited by the memory available on the device, so for heavy batch resizing the backend image resizer is the better choice.
