LinkedIn Image Resizer — Free Online

Use the landscape canvas for a headline illustration that needs to remain recognizable when displayed beside a link. Keep any essential wording short and large enough to read at feed size. A slide full of tiny chart labels may be better shared as a document rather than compressed into a single preview image. The dimensions alone cannot solve an overcrowded composition.

For a square announcement, check the balance between the speaker, product or event photograph and its surrounding space. The tool does not generate text or change the content of a chart. A profile source should leave room around the face because the destination can apply a circular mask. Use LinkedIn Banner Resizer for the separate personal background area.

LinkedIn documents its link-preview shape in Page post preview guidance. Preparing that image does not install Open Graph metadata on your website or clear a previously cached link preview. After downloading, test the actual post composer. If the wrong image appears when sharing a URL, investigate the website preview configuration as well as the image file rather than repeatedly resizing an already correct canvas.

Open one image and check the width and height before processing. Selecting a preset fills both fields; you can replace those values with custom pixel dimensions. The default fit fills the canvas with a centered crop. When the shapes differ, the fit controls let you keep the whole picture with padding instead, or deliberately stretch it. Padding is white for JPEG and can be transparent for PNG or WebP. The aspect lock controls dimension edits; it does not protect an off-center subject from a crop.

The resizer accepts JPG, JPEG, PNG, WebP, HEIC and AVIF. HEIC needs its browser decoder, downloaded when first required; AVIF support depends on the browser. JPEG, PNG and WebP retain their format, while HEIC is exported as JPEG and AVIF as PNG. If the destination needs another format, use Image to JPG or the corresponding converter. A correct filename extension alone does not mean that a file has been converted. This page resizes a still image, not a video or an animated sequence.

Review the downloaded copy at its intended display size as well as at full resolution. Enlarging a small source creates more pixels but cannot restore missing detail. Resizing sets pixel dimensions, not a guaranteed maximum in KB; Reduce Image Size handles a file budget afterward. Keep the original for another attempt, since repeatedly saving a JPEG can accumulate visible damage. The tool processes files locally without signup and does not publish to another service. On mobile, keep the tab open until the result is ready, then confirm that the saved file is the newly generated copy.
