Toolzilla's Image Tools let you compress, resize, convert, crop, rotate, watermark, and apply effects to photos and graphics — all in your browser. Ideal for freelancers preparing portfolio images, social media assets, or client deliverables without Photoshop. No uploads means your images stay private on your device.
Reduce JPG, PNG, and WebP file sizes while keeping acceptable visual quality.
Tip: Compress hero images before adding them to proposals or websites.
Change image dimensions by exact pixels or percentage.
Tip: Resize to platform-specific dimensions — see our Social Media Image Sizes blog article.
Convert between JPG, PNG, and WebP formats.
Tip: Use WebP for web images (smaller files) and PNG when you need transparency.
Crop images to custom dimensions or preset social media ratios.
Tip: Crop to 1:1 for Instagram posts or 16:9 for YouTube thumbnails.
Fix orientation by rotating 90°, 180°, or 270°, or flip horizontally/vertically.
Tip: Straighten scanned documents before converting to PDF for a professional look.
Add a text watermark to protect images before sharing online.
Tip: Watermark portfolio previews before sending to prospects who have not yet paid.
Apply black-and-white, sepia, or colour-invert effects.
Tip: Grayscale reduces file size slightly and works well for formal document illustrations.
Some quality loss is normal with lossy formats like JPG. Start at 80% quality and lower gradually until you find an acceptable balance between size and clarity.
Limits depend on your device memory. Most images under 20 MB process quickly. Resize very large camera RAW exports before uploading.
No. All image processing happens locally in your browser using the Canvas API.
PNG preserves transparency and sharp edges. Use JPG for photographs and WebP for modern websites.
