About TinyResize

TinyResize is a free browser-based image resizing tool with verified presets for 200+ platform sizes. Every preset includes the official recommended dimensions, accepted formats, file size limits, and platform-specific tips.

The tool runs entirely in your browser — images are never uploaded to a server. Pick a preset, position your crop, and download the result. That's it.

Every social media platform, marketplace, and online service has different image requirements. Getting dimensions wrong means your images get cropped awkwardly, stretched, rejected on upload, or just look unprofessional.

Finding the right specs usually means digging through help docs that are often outdated, buried three clicks deep, or contradicted by other sources. TinyResize puts the verified answer and the resizing tool on the same page.

Every preset is checked against the platform's official documentation. We include the date each spec was last verified, shown on every tool page so you know exactly how current the data is.

When platforms change their requirements, we update the data and note the change. If you spot an outdated spec, let us know and we'll fix it within 24 hours.

TinyResize processes images using your browser's built-in Canvas API. Nothing is uploaded. Nothing is stored. Your image goes from your device to your screen to your download folder — the internet is never involved in the resize itself.

TinyResize is an independent project built and maintained by a small team. The goal is straightforward: provide the most reliable, fastest image resizing experience without the sign-ups, watermarks, and upsells that plague most online tools.
