A side-by-side comparison of two popular online image resizers.

|---|---|---|
| Processing | In-browser (WASM) | Server-side upload |
| Privacy | Images never leave your device | Files uploaded to their servers |
| Resize Formats | JPEG, PNG, GIF, WebP, HEIC | JPEG, PNG, GIF, WebP, BMP, TIFF |
| Unit Support | px, %, in, cm, mm | Pixels only |
| Batch Processing | Yes | Yes |
| Crop | Yes (aspect-ratio presets) | Yes |
| Pricing | Free (no account needed) | Free tier with limits; paid plans |
| API | No | Yes (paid) |
| File Size Limit | Depends on device memory | Free: 25 MB |
The biggest difference is how each tool handles your files. ImageResizer Studio processes images entirely in your browser using WebAssembly (JSquash). Your files never leave your device — there is no server upload and no data retention.
iLoveIMG (part of the iLovePDF family) uploads your files to their servers for processing. While they have a privacy policy and delete files after 2 hours, your data does transit over the network and is temporarily stored on third-party infrastructure.
ImageResizer Studio supports 5 unit types: pixels (px), percent (%), inches (in), centimeters (cm), and millimeters (mm). This makes it useful for both web design (px and %) and print workflows (in, cm, mm at 300 DPI).
iLoveIMG only supports pixel-based resizing. You specify target width and height in pixels. There is no way to resize by physical dimensions or percentage, which limits its usefulness for print preparation.
iLoveIMG supports a wider range of input formats including BMP and TIFF, which ImageResizer Studio does not currently handle. Both tools support the most common web formats: JPEG, PNG, GIF, and WebP.
ImageResizer Studioincludes HEIC/HEIF support — Apple’s default photo format — which iLoveIMG does not handle natively. Both tools allow output format conversion (e.g., JPEG to PNG).
iLoveIMG offers a broader suite: compress, resize, crop, rotate, watermark, format converter, and a PDF editor (via the sister site iLovePDF). It also has a paid API for developers who want to integrate image processing into their applications.
ImageResizer Studio focuses on resize, crop, compress, and convert. It offers DPI controls, aspect-ratio presets, exact target file-size compression (resize to 20KB–1MB), and unit-aware output — features that go deeper into the resize workflow rather than broad tool coverage.
ImageResizer Studio is completely free for all resizing features — no account required, no file count limits, no watermarks.
iLoveIMG offers a free tier with limited daily processing and a maximum file size of 25 MB. Premium plans remove limits and unlock the API, batch processing with larger files, and priority processing.
Choose ImageResizer Studio if you prioritize privacy (browser-only processing), need physical print units (in, cm, mm), or want to resize HEIC photos from your iPhone — all for free with no account required.
Choose iLoveIMG if you need BMP/TIFF support, a wider suite of tools (watermark, rotate, PDF), or a paid API for developer integration. Be aware that your files are uploaded to their servers during processing.

It depends on your needs. ImageResizer Studio offers browser-based processing (no upload), 5 unit types (px, %, in, cm, mm), and HEIC support. iLoveIMG supports BMP/TIFF, has a wider tool suite, and offers a paid API.
iLoveIMG has a free tier with daily limits and a 25 MB file size cap. Premium plans remove limits and unlock the API. ImageResizer Studio is completely free with no file count limits and no account required.
No, iLoveIMG does not natively support HEIC/HEIF (Apple's photo format). ImageResizer Studio supports HEIC for resize, crop, and format conversion.
