Two popular image resizers compared on privacy, features, and format support.

|---|---|---|
| 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, HEIC |
| Unit Support | px, %, in, cm, mm | Pixels only |
| Crop | Yes (aspect-ratio presets) | Yes |
| Compress | Yes (target file size) | Yes |
| Convert | Yes (any → any) | Yes |
| Batch Processing | Yes | Yes (paid only) |
| Pricing | Free (no account needed) | Freemium (paid for batch, no ads) |
| Ads | None | Yes (free tier) |
ImageResizer Studio processes images entirely in your browser using WebAssembly. Files are never uploaded, never stored on servers, and automatically cleaned from memory after download. This approach is fundamentally different from server-based tools.
ImageResizer.com uploads your files to their servers for processing. They have a stated privacy policy and delete files after processing, but your images do transit the network and are temporarily stored on third-party infrastructure. For sensitive or confidential images, this may be a concern.
This is one of the clearest differentiators. ImageResizer Studio supports 5 unit types — pixels, percent, inches, centimeters, and millimeters. You can resize an image to exactly 5×7 inches for a print, or scale it by 50%, all without doing unit conversion yourself.
ImageResizer.com only supports pixel-based resizing. You specify a target width and height in pixels. To resize to a physical print dimension, you would need to manually calculate the pixel dimensions at your target DPI.
ImageResizer.com offers a broader set of tools beyond resizing: image compression, format conversion, cropping, rotation, flipping, and a metadata viewer. It also has a paid API for developers.
ImageResizer Studio focuses on depth in resize, crop, compress, and convert workflows: DPI-aware output, aspect-ratio presets, exact target file-size compression (resize to 20KB–1MB), and unit-aware dimension controls. The toolset is narrower but goes deeper into the resize workflow.
ImageResizer.com supports a wide range of formats including BMP, TIFF, and HEIC in addition to the standard web formats (JPEG, PNG, GIF, WebP). This broader format support can be useful for users working with legacy or print-oriented file types.
ImageResizer Studio supports JPEG, PNG, GIF, WebP, and HEIC — covering the most common web and mobile photo formats. Both tools allow output format conversion between supported formats.
ImageResizer Studio is entirely free. No account, no watermarks, no ads, no file count limits. The tool is supported by the open web and focused on delivering value without a paywall.
ImageResizer.com uses a freemium model. The free tier includes ads and limits on batch processing. Paid plans remove ads, unlock batch processing, and provide priority support. An API is available on paid plans.
Choose ImageResizer Studio if you want browser-based privacy (no uploads), need physical print units (in, cm, mm), prefer no ads or account requirements, and value deep resize controls like exact target file sizes and DPI output.
Choose ImageResizer.com if you need broader format support (BMP, TIFF), want an all-in-one tool suite (metadata viewer, rotation, compression), or need a paid API for developer integration. Be aware that batch processing requires a paid plan.

ImageResizer Studio processes images entirely in your browser (no upload), supports 5 unit types (px, %, in, cm, mm), and includes HEIC support. ImageResizer.com uploads files to their servers, supports more input formats (BMP, TIFF), and has a wider tool suite but requires a paid plan for batch processing.
ImageResizer.com has a free tier with ads and a 1 file-at-a-time limit. Batch processing and ad-free experience require a paid plan. ImageResizer Studio is completely free with no limits.
ImageResizer Studio is more private — images are processed entirely in your browser and never uploaded to any server. ImageResizer.com uploads files to their servers for processing.
