Why is my logo PNG blurry and how do I fix it?

Find where the softness first appears

Exporting a larger PNG helps when the original artwork contains enough detail. Enlarging a small raster file cannot recover the exact curves and letterforms of the original vector logo.

Open the PNG itself before changing the website or exporting again. Inspect it at its intended use size and at a pixel-level view. Then compare it with the approved source and the uploaded version.

Use the following checks to identify the stage that needs attention. They do not assume every soft edge has the same cause.

• Soft in the original artwork: find a better source or review the design's small-size version.
• Sharp source, soft downloaded PNG: check the export dimensions, bounds and rasterization settings.
• Sharp download, soft on the website or in email: check which image is being served and how it is scaled.
• Sharp mark, unreadable tiny lettering: review the logo's minimum size or use an approved simpler version.

Check what the source actually contains

A true vector master gives you shapes that can be rendered at a new size. An SVG can also contain embedded bitmap images, so an SVG filename alone does not establish that the logo is vector artwork.

If your source is a small PNG copied from an old website, ask for the original working file or a verified vector export. Exporting that small PNG again at a larger size adds estimated pixels. Adobe describes upsampling as a process that can introduce artifacts and cannot add detail absent from the original.

If the master is unavailable, rebuilding or tracing the mark is a separate design task. Compare reconstructed letterforms and shapes with an approved reference before using them as a new master.

Compare file pixels with displayed pixels

Use the actual displayed size rather than the width you expected the layout to use. Browser developer tools can help check the rendered image box. Account for responsive breakpoints and any transform that enlarges the logo.

Resizing the existing 200 × 50 PNG to 400 × 100 does not create an equivalent export from vector artwork. Both files can have the same dimensions while containing different edge detail. Device pixel ratio is the relationship between physical display pixels and CSS pixels.

For the full calculation and handoff examples, see logo PNG sizes for websites and email.

Here is an illustrative example using the fictional Morrow Quay logo, not an actual customer test:

• The header displays the logo at 200 × 50 CSS pixels.
• The uploaded PNG contains only 200 × 50 pixels.
• A 2× target calls for 400 × 100 pixels.
• Re-export the vector artwork at 400 × 100, while keeping the display at 200 × 50.

Check the image the destination really serves

A large original does not help if the page loads a smaller generated thumbnail. Check the selected resource and its pixel dimensions. For responsive images, the browser's currentSrc property identifies the chosen image URL. Compare that resource with the original upload.

If the served file is smaller, inspect the CMS image settings or ask the developer to use the appropriate asset. If its dimensions are correct, compare the files visually before blaming optimization. A service may resize, convert or otherwise process an upload, but establish which change actually occurred.

PNG uses lossless compression. Reducing its storage size with a genuinely lossless process does not itself blur the pixels. Converting a previously damaged JPEG to PNG also preserves the existing damage. Check the entire processing path, including resizing or lossy conversion, rather than treating “compression” as a single operation.

Inspect padding and edge settings

Transparent padding uses part of the image's dimensions. A 400-pixel-wide canvas with a 200-pixel-wide mark has only 200 horizontal pixels describing the visible logo. If you display the whole image at a larger size to make the mark look bigger, you also enlarge those pixels. Correct accidental bounds at the source while preserving approved clear space.

Some smoothing along curves is normal anti-aliasing. Judge the asset at its real use size as well as zoomed in. Extremely small lettering or thin strokes may need an approved small-size alternative even when the export dimensions are technically sufficient.

Figma offers PNG image resampling choices: Detailed is the default, and Basic uses nearest-neighbor sampling. Compare the settings on your actual artwork; a harder-looking edge is not automatically a more faithful result. Figma also accepts a fixed export width such as 400w.

Illustrator provides native Export for Screens for raster outputs at chosen scales. Its PNG export options include anti-aliasing controls. Check a fresh export from the original artwork rather than repeatedly resizing the previous PNG.

Re-export and verify the fix

Create one replacement at the required dimensions before regenerating the whole package. Put it in the same placement and compare it with the previous version. Check the served file again so an old thumbnail or cached asset does not confuse the result.

For an approved SVG source, logopack.app Pro's custom PNG sizes can help create destination-specific files as part of a logo package. This is an export workflow, not a vectorization or low-resolution logo repair service.

If the destination supports SVG, a verified vector version may be the better fit. Our file format guide explains that choice, and our Figma export guide covers preparing the source.

Call the issue resolved when the correct file is sharp enough at the intended size, the background works, and the receiving system preserves the intended proportions. Keep the checked master and export settings for the next handoff.
