Image Tools: Everything in One Place
Image editing used to mean installing heavy software or uploading your photos to a random website. Vizo Tool's image tools work differently: every editor runs 100% in your browser, so your pictures never leave your device.
From compressing a 4MB photo to 50KB for a job form, to cropping a passport photo to the exact official dimensions, to removing a background in seconds — the whole suite is free, unlimited and ready when you are.
Why Use Image Tools?
Free, private and built for real workflows.
100% Private — Zero Uploads
All processing happens locally with the Canvas API. Your images never touch a server, so nothing can be stored, sold or leaked.
Free & Unlimited
No sign-ups, no watermarks, no daily limits. Compress, crop and convert as many images as you want, forever.
Works on Any Device
Desktop, tablet or phone — every tool is fully responsive and works offline-capable in the browser. No apps to install.
Professional Results in Seconds
Passport sizes for 25+ countries, social media presets, target-size compression and AI background removal — all in a few clicks.
What’s Inside
Every tool ships with the essentials and then some.
Target-Size Compression
Shrink images to exactly 50KB, 100KB or 200KB with a smart quality algorithm that keeps photos looking sharp.
Preset Ratios & Passport Sizes
Crop to passport, A4, Instagram, YouTube and 20+ more presets, or define a fully custom aspect ratio.
Format Conversion & HEIC
Convert between JPG, PNG, WEBP and AVIF — including HEIC files straight from your iPhone.
AI Background Removal
Cut out any subject automatically, swap in colors or images, and export a transparent PNG — all on-device.
How to Use Image Tools
A simple, repeatable workflow.
Open the tool you need
Pick compress, resize, crop, flip, watermark or remove background from the grid below.
Add your image
Drag & drop, click to browse, or paste from your clipboard. Files stay on your device.
Tune the settings
Choose a target size, ratio, format, watermark style or background — preview updates instantly.
Download the result
Export as PNG, JPG or WEBP with quality control. Done — nothing was ever uploaded.
Common Use Cases
- Reducing image size for job applications, college portals and email attachments
- Making compliant passport and visa photos at home
- Preparing social media posts at the exact platform dimensions
- Removing backgrounds for product listings and thumbnails
- Protecting photography with text or logo watermarks
Best Practices
- Always compress from the original file — recompressing an already-compressed image loses quality.
- Use WEBP for web images, JPG for universal compatibility, PNG for logos and text.
- Crop from the highest-resolution master to keep output sharp.
- Preview the result at 100% zoom before downloading.
Common Mistakes to Avoid
Small habits that save you time and frustration.
Compressing a PNG photo instead of converting it to JPG or WEBP first.
Forgetting that resizing down to a small size loses detail you can't get back.
Using a low-quality export when a modern format like WEBP would halve the size.
