Enter width and height, lock aspect ratio, choose JPEG PNG or WebP, adjust quality, and download — all elaborato localmente nel browser with transformImage. Nessun account, nessun upload, completamente gratuito.

Cosa fa questo strumento

Images rarely arrive at the exact size a platform requires. Social posts need specific aspect ratios, CMS thumbnails have pixel caps, email signatures want small footprints, and print-adjacent workflows sometimes need precise dimensions. A reliable resizer lets you hit those targets without opening desktop software or trusting a cloud service with your files.

The XConverters resize tool shows your image natural dimensions after upload and lets you type target width and height in pixels. Keep aspect ratio is enabled by default so changing one dimension automatically updates the other — ideal when you know the width a layout needs but want proportions preserved. Turn it off when you need exact non-proportional dimensions for specialized layouts.

An allow upscale toggle controls whether the tool enlarges images beyond their original resolution. Upscale is off by default to avoid blurry enlargements, but you can enable it when you intentionally need a larger canvas. Output format supports JPEG, PNG, and WebP with a cursore qualità for JPEG and WebP. transformImage handles decoding, scaling, and re-encoding entirely nel browser.

Because nothing is uploaded, client photos, product shots, and personal images stay on il tuo dispositivo. XConverters is free with senza registrazione, making this resizer suitable for quick one-off edits and repeated daily workflows alike.
