A logo usually looks blurry because the image file does not contain enough pixel detail for the size at which it is being shown. The most reliable fix is to use the original vector artwork, or export a new raster image from that artwork at the dimensions the website, app, or printer needs.
Why logos look blurry
PNG and JPEG files are raster images: they are made of a fixed grid of pixels. Enlarge one beyond the detail in that grid and the edges can look soft or visibly pixelated. Resizing does not add the original design detail that the file never contained. Adobe explains the difference between raster and vector images.

A logo can also look soft when it was exported at too few pixels for its placement, enlarged after export, or resized or converted by a website or app. The right fix depends on which stage is introducing the softness.

Check whether your logo file is vector or raster
Vector artwork is built from shapes and paths rather than a fixed pixel grid, so it can be resized without the same resolution limit. Common vector-capable formats include SVG, AI, EPS, and PDF. Raster formats include PNG and JPEG. A PDF is not automatically vector: it can contain a raster image, so check the file’s contents rather than relying only on its extension. Adobe’s file guide describes the distinction.
#1 Best Overall
If you can, inspect the file in an editor that shows its artwork structure. Zooming in may reveal pixelation, but it is not a definitive test for a PDF that combines vector and raster elements.
Fix the logo based on where it gets blurry
It blurs when you enlarge it
- Ask the original designer, brand team, or person who created it for the vector master and any ready-to-use exports.
- Place the vector file into the target document or upload it directly if the destination accepts that format.
- If the destination requires pixels, export a fresh raster image from the vector master at the intended display dimensions. Avoid enlarging a small PNG or JPEG repeatedly.
If no vector master exists, increasing a small raster file’s dimensions cannot restore detail that is absent from the source. You can use it at an appropriate size or have the artwork recreated as vector paths.
Rank #2
It looks blurry only after export
Check the exported file’s pixel dimensions and compare them with the size at which it is displayed. Raster output remains pixel-based even when it was created from vector artwork; showing it larger than its pixel dimensions can soften edges. In Illustrator, check the export format and resolution settings. Adobe’s Illustrator export guide explains the available export controls.
For web graphics with horizontal or vertical strokes, aligning those segments to the pixel grid can help them appear crisp. Adobe also recommends SVG for web graphics where the destination supports it. See Adobe’s web-graphics guidance.
Rank #3
It looks blurry on a website or phone
- Check whether the website or app accepts SVG or another vector format.
- Find out whether its content-management system or image pipeline converts uploaded files to raster.
- Compare the delivered image’s pixel dimensions with its actual rendered size.
- If raster is required, export a new image at the target pixel dimensions and check its appearance on the destination.
SVG can retain resolution-independent scaling, but only if the destination preserves and renders it as vector artwork. Platform requirements differ, so follow the current file and sizing specifications for the specific site or app. Adobe describes SVG’s usefulness for mobile publishing and zooming in its web-graphics guidance.
It looks blurry in print
Ask the printer for the required file type, final physical size, and resolution. A vector master is a robust source when the logo may need different print sizes. If the printer requests raster artwork, export it for the actual physical dimensions and the resolution they specify.
PPI means pixels per inch in an image; DPI means dots per inch from a printer. They relate to print output but are not interchangeable. A resolution figure without the intended physical size does not tell you whether a raster file has enough pixels. Changing a resolution metadata value cannot recreate missing image detail. Adobe provides general guidance, not one rule for every print process; use the printer’s specifications. Adobe’s raster and vector guide gives further context.
Choose the right file for the destination
| Situation | Preferred asset | What to check |
|---|---|---|
| The logo needs to work at many sizes | Vector master, such as SVG, AI, EPS, or vector PDF | Confirm that the file contains vector artwork; a PDF may contain raster content. |
| A website or app accepts vector graphics | SVG or another accepted vector format | Confirm the destination preserves and renders the vector asset. |
| The destination requires pixels or transparency | PNG exported from the vector master | Match the required pixel dimensions and transparency needs. PNG is lossless and supports transparency. |
| The destination requests JPEG | JPEG exported at the required dimensions | JPEG is raster and lossy; use it only when its format and lack of transparency suit the placement. |
| A print workflow requests raster output | Raster export at the specified dimensions and resolution | Obtain the printer’s specifications and distinguish PPI from DPI. |
| Only a small raster file remains | Use it at an appropriate size, or retrieve or recreate a vector master | Upscaling cannot recover detail missing from the original file. |
Illustrator’s export options vary by format and let you set controls such as rasterization resolution. You do not need a particular application just to use a logo, but a vector editor can help if you need to edit or export a master.
