Resize Image · client-side FFmpeg

FileForge is bringing FFmpeg entirely inside your browser tab — nothing uploads. Enable this tool by turning on cross-origin isolation in your deployment (see ffmpegwasm.netlify.app), or use the desktop CLI in the meantime.

About Resize Image

Resize to exact pixel dimensions or by percentage, with an aspect-ratio lock so nothing gets stretched. Rendering uses high-quality canvas smoothing. Everything happens locally in your browser: nothing is uploaded, stored, or logged. This focused Resize Image page is designed for people preparing exact dimensions for profiles, websites, documents, listings, and social posts. It opens directly to the working tool, rather than hiding the function inside a general converter or account dashboard.

The browser decodes the image into a local canvas, applies the requested operation, and encodes the result directly into a downloadable file. Your filename and file contents stay on the device. There is no upload queue, temporary cloud copy, account record, or server-side conversion job to delete later. That makes the tool practical for personal records, work material, and drafts that should not be handed to an unknown processing service.

The operation stays focused on set exact dimensions or scale. You can inspect the result immediately and repeat the task with different settings without a quota or watermark. Processing speed and maximum size depend on your browser and available device memory, which is the honest trade-off for doing the work locally.

FileForge charges nothing for this tool and does not add a watermark. Once the page and its processing engine have loaded, the operation can continue without sending the file over the network. Use the numbered steps below, download the result, and review it before replacing an original file.
