ConvertImgi.in is a free, browser-based image conversion and optimization tool for photographers, bloggers, online sellers, developers and anyone who just needs to turn one image format into another without installing software. Below is a full breakdown of every feature, supported format, and use case - plus how ConvertImgi.in connects with imgi.in's free AI image generator if you need to create images from scratch before converting or resizing them.
Everything you need for fast, private, high-quality image conversion in one free web app.
Convert up to 10 images at once instead of processing files one by one - a real bulk image converter for busy workflows.
Drag and drop your photos directly into the browser, or use the file picker - no installation, plugin or extension required.
Every conversion runs locally using WebAssembly - your images are never uploaded to a server, making it safe for sensitive or personal photos.
Reduce file size for faster websites, email attachments, and messaging apps using adjustable compression and quality controls.
Resize by percentage or exact pixel width and height across an entire batch of images in a single pass.
Rotate images 90°, 180° or 270° to fix orientation issues before download.
Apply grayscale, sepia, vintage, invert, blur or sharpen filters, plus automatic enhancement for a polished look.
Rename every file in a batch using a custom pattern like photo_{num}, ready for upload without manual renaming.
Switch between RGB, CMYK and grayscale, and set DPI resolution from 72 up to 1200 for print-ready output.
Download all your converted images together as a single ZIP file instead of saving each one individually.
