Free Online Image Tools
ToolFlip's image tools solve the two most common image tasks on the web: resizing images to specific dimensions and converting iPhone photos to a format that actually works everywhere. Both tools run entirely in your browser — your images are never uploaded to any server, never stored in any database, and never seen by anyone but you.
Image Resizer. The resizer lets you set exact pixel dimensions or scale by percentage, with a lock toggle to maintain aspect ratio. It accepts JPG, PNG, WebP, GIF, and BMP files and outputs JPG or PNG with adjustable quality. Common use cases include preparing product photos for Shopify (which recommends 2048 × 2048 px), resizing screenshots for documentation, creating social media images at platform-specific sizes (1200 × 630 for Open Graph, 1080 × 1080 for Instagram), and reducing file size for WordPress uploads where large images slow page load times. The tool shows file size before and after so you can gauge the trade-off between quality and download speed.
HEIC to JPG Converter. Every iPhone since iOS 11 saves photos in HEIC format by default. HEIC files are roughly half the size of equivalent JPGs, which saves storage on your phone — but Windows PCs, most CMS platforms (WordPress, Squarespace, Wix), and many web browsers cannot open them natively. The converter turns your HEIC files into standard JPG with a quality slider from 1% to 100%. Drag and drop a file, adjust quality, and download the converted JPG. Real estate agents, photographers delivering to clients on Windows, and anyone uploading iPhone photos to a website that rejects HEIC will find this useful.
Privacy by design. Image tools are the category where privacy matters most — photos often contain faces, locations, and personal moments. ToolFlip processes everything client-side using the browser's Canvas API and JavaScript. No files are transmitted over the network. You can verify this by opening your browser's network inspector while using either tool — you will see zero upload requests. The original file stays on your device, and the converted output is generated as a local blob URL that you download directly.
Both tools are designed for speed. Drop a file, adjust settings, and download the result. No accounts, no watermarks, no limits on how many images you process. More image tools — including batch processing, format conversion between PNG, WebP, and AVIF, and image compression — are planned for future releases.

Frequently Asked Questions
ToolFlip currently offers two free image tools: an Image Resizer for changing dimensions and file size of JPG, PNG, and WebP images, and a HEIC to JPG Converter for turning iPhone photos into a universally compatible format. More image tools are planned.
No. Both image tools process files entirely in your browser using JavaScript and the Canvas API. Your images never leave your device — there are no server uploads, no cloud storage, and no data retention. You can verify this by disconnecting from the internet after the page loads.
The Image Resizer accepts JPG, PNG, WebP, GIF, and BMP files and outputs JPG or PNG. The HEIC to JPG Converter accepts .heic and .heif files (the default format on iPhones since iOS 11) and converts them to standard JPG files with adjustable quality.
Since processing happens in your browser, the limit depends on your device's available memory. Most modern devices handle images up to 20-30 MB without issues. For very large files (50 MB+), you may experience slower processing on older devices.
Apple adopted HEIC (High Efficiency Image Container) starting with iOS 11 because it produces files roughly 50% smaller than JPG at the same visual quality, saving storage space. The trade-off is that Windows, many CMS platforms, and older browsers cannot open HEIC files natively, which is why a converter is useful.
