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.
iLovePDF 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).
iLovePDF 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.
iLovePDF excels at PDF operations: merge, split, compress, convert, watermark, and more. If your workflow involves both PDFs and images, iLovePDF provides a single platform for both.
ImageResizer Studio focuses exclusively on image processing — resize, crop, compress, and convert. It offers DPI controls, aspect-ratio presets, exact target file-size compression, and unit-aware output for deeper image workflows.
iLovePDF supports a wider range of image 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 iLovePDF does not handle natively. Both tools allow output format conversion (e.g., JPEG to PNG).
ImageResizer Studio is completely free for all resizing features — no account required, no file count limits, no watermarks.
iLovePDF offers a free tier with limited daily processing. 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 iLovePDF if you need PDF tools alongside image processing, BMP/TIFF support, or a paid API for developer integration. Be aware that your files are uploaded to their servers during processing.
