Batch image converter
Converting images one at a time is tedious when you have a folder of screenshots, a set of photos to email, or a batch of assets for a website. This batch converter lets you process multiple images in one session — entirely in your browser.
Common use cases include converting many screenshots to JPG, preparing photos for email attachments, creating WebP assets for faster websites, resizing multiple images at once, and downloading all converted files as a single ZIP archive.
Everything runs locally on your device using the Canvas API. Images are not sent to any server, and no account is required. Your files stay private from start to finish.
- Use cases: screenshots, email photos, WebP assets, bulk resizing, ZIP download
