ShiftTools Image Converter lets you convert image formats locally in your web browser. No files are uploaded to any server — the entire process runs directly on your device using HTML5 Canvas and browser Web APIs. Convert raw photos, logos, mockups, or custom graphics up to any size.

How to Convert Images
Click "Browse Files" or drag & drop one or multiple images into the converter.
Select your target format (PNG, JPG, WEBP, AVIF, BMP, ICO, GIF, TIFF) from the global chips or per-file settings.
Adjust the quality slider (for lossy formats) or select custom dimension presets (like Favicon sizes).
Choose a background backdrop fill (white, black, or transparent) if converting transparent images.
Click "Convert All Images" to process your files instantly.
Click the download icon on each file, or click "Download All (ZIP)" to export the entire batch at once.
Advanced Client-Side Resizing
Need custom resolutions or web-optimized sizes? The tool includes built-in scale options (75%, 50%, 25%) and exact dimension presets to output standard browser Favicons (16×16 px, 32×32 px, 64×64 px, up to 256×256 px). Great for generating multi-size app icons and web assets without any software installation.
Frequently Asked Questions
WEBP provides superior compression for web performance. Drag and drop your PNG images into ShiftTools, choose WEBP as your target format, adjust the quality slider to 85%-90%, and click Convert All to reduce image file size by up to 70% while maintaining crisp quality.
JPG is a lossy format that discards color data to make files tiny. PNG is 100% lossless, so when converting JPG to PNG, the PNG encoder must store exact pixel values for all compression artifacts and noise, resulting in a larger file size.
Select ICO as your output format, select your dimension preset (16×16 px, 32×32 px, or 64×64 px), and click Convert. ShiftTools resizes your graphics and exports standard favicon files ready for your website.
Yes, 100%. All image format conversions run locally inside your browser using HTML5 Canvas & Web API technology. Your photos and graphics never touch any remote server.
Yes. You can import as many files as you like. They will be queued, converted in batch using your global settings (or custom formats selected for individual files), and you can download them all bundled into a single ZIP archive.
Yes. When converting a transparent image (e.g. PNG) to a format that doesn't support transparency (e.g. JPG), you can select a white, black, or custom background backdrop fill to avoid visual bugs. Selecting Transparent keeps transparency intact for formats like PNG, WEBP, and AVIF.
No. Because all files are processed locally on your hardware rather than uploaded to cloud servers, there is no server-imposed file size limit. You can easily process large raw digital photography files directly.
