Why resize images before uploading them online?

Too large images slow down websites, increase loading times and penalize placement on Google. Resizing photos before uploading is one of the simplest and most effective operations to optimize the performance of a site. With censorpic's online image scaler you can do it in seconds, without software, directly in your browser.

Reduce the weight of images for the web

A high-resolution photographic image can weigh several MB. For a website, ideal size rarely exceeds 1200–1600px width. Resize and optimize quality With the slider it can reduce the weight of the file by 80% or more, drastically improving the core web vitals and the speed of loading pages.

Resize for Social Networks

Each platform has different recommended dimensions: Facebook prefers 1200 × 630px images, 1200 × 627px LinkedIn, 1600 × 900px Twitter. Setting the exact dimensions before loading ensures that images are not compressed or automatically cropped from the platform, while maintaining the original quality.

JPG, PNG or WEBP: which format to choose?

JPG It is the best choice for complex photographs and images: excellent compression with slight loss of quality, light files. PNG It is ideal for logos, graphics, screenshots and text images: lossless compression, support transparency. WebP It offers the best of both: 30% lighter files than JPG for the same quality, and is supported by all modern browsers.

Proportion block: no more distortions

The “Keep original proportions” checkbox is active by default for a specific reason: change only width or height without updating the other value crushes or lengthens the image in a visually ugly way. With the block active, the calculation takes place automatically — just enter one dimension.
