ImageWizo is a fast, free, and private suite of browser-based image editing and PDF management tools. Compress, resize, crop, watermark, convert formats, enhance photo details, upscale resolution, remove backgrounds, and merge, split, or compress PDF documents directly on your device.
Local File Processing: ImageWizo processes supported files directly in your web browser using HTML5 Canvas, JavaScript, and on-device WebAssembly/GPU acceleration where applicable. File processing occurs locally rather than being sent to an ImageWizo processing server.
Explore our specialized tools for photographic workflows, image conversions, and PDF document processing:
Compress JPEG, PNG, and WebP images to reduce file sizes based on your chosen quality level. Features batch compression and custom quality sliders.

Shrink bulky PDF file sizes by re-encoding pages with adjustable resolution scaling and quality presets directly in your browser.
ImageWizo performs supported file processing locally in your browser. When you select a photo or PDF file:
The file is loaded directly into an ArrayBuffer or Blob URL within your device RAM. Your selected files are processed locally rather than uploaded to an ImageWizo processing server.
Image resampling, pixel manipulations, and PDF byte streams are transformed using your device's native CPU and GPU graphics pipelines.
Your browser encodes the final binary file and triggers an immediate local download. Once you navigate away, memory references are disposed.
Selecting the ideal output format is critical for balancing visual quality and download speed. Here is how our supported formats compare:
Best For: Standard digital photos, social media posts, and print galleries.
Pros & Cons: Universal device compatibility and excellent lossy compression. Does NOT support transparency.
Best For: Logos, website icons, UI mockups, diagrams, and sharp text screenshots.
Pros & Cons: Lossless quality and full alpha transparency support. Produces larger file sizes for complex photos.
Best For: Modern web publishing, mobile applications, and ecommerce catalogs.
Pros & Cons: Can often be smaller depending on image content, format, dimensions and quality settings. Supports both transparency and high compression.
Compress hero images, convert banners to WebP, and ensure mobile landing pages achieve high Core Web Vitals scores.
Crop portrait photos to standard passport ratios, compress resume PDFs below government upload limits, and convert scans.
Remove distracting product backgrounds, stamp branded watermarks, and batch-resize catalog pictures for online stores.
Invert 35mm film negatives into positive photographs, adjust color cast tints, and combine multiple scan files into single PDF records.
Because all tasks process in your browser sandbox, very large image batches or hundreds of PDF pages rely on your device's available RAM. For best responsiveness on mobile devices, process files in batches of 10 to 20 items.
File processing occurs locally in your browser rather than being sent to an ImageWizo processing server.
