Transparent files for a client proofing round: tips

You send a logo or product graphic for review, but it arrives with a white box around it, looks different on a dark background, or will not open for the client. A successful export depends on both the file format and whether the source image actually has transparency.

Use the Image Converter to convert image files in your browser, then check the result against more than one background before you send it. Keep the original editable file too, so you can make changes without losing the clean source.

Prepare and check the transparent file

1. Open the Image Converter and select the image or images you need to convert. It supports JPG, PNG, WEBP, GIF, BMP, ICO, and TIFF, with up to 50 images at once.
2. Choose an output format that supports the transparency and fits the client's workflow. PNG is usually the safest option for logos and graphics that need clear edges across common apps.
3. Convert the file and save the output separately from the original. Use a filename that identifies the artwork and format, such as northstar-logo-transparent.png.
4. Open the exported file in an image viewer or editor that shows transparency, then inspect it against both a light and a dark background. Check the edges closely and make sure the intended empty areas are see-through.

If you are sending several versions, give each one a clear name and include a separate preview showing how the graphic is intended to look in the design. A flattened preview is useful for review, but label it as a preview so it is not mistaken for the transparent deliverable.

What the result means

The image has a checkerboard or transparent area in the viewer

The checkerboard is a common way for image software to show transparent pixels. It is not part of the artwork. If the image also looks right over light and dark backgrounds, the export is likely ready to share.

The image looks white in one viewer

Some viewers display transparent areas as white instead of showing a checkerboard. That does not necessarily mean the file has a white background. Open it in a viewer that indicates transparency, or place it over a colored background in an editor to check.

A white rectangle appears over every background

The white pixels may be part of the image rather than transparent pixels. Changing a JPG to PNG does not remove a background that was already flattened into the picture. Go back to the editable source and export it with transparency, or remove the background before converting.

The edge looks pale on a dark background

A light fringe can mean the edge pixels were blended with white when the artwork was previously flattened. This is sometimes called a matte. Exporting that image to another transparent format will not restore the original edge colors. Use the clean source file or remove the white matte in an image editor, then check the result again.

Choose a format the client can use

PNG for predictable proofing

PNG supports transparency with smooth, partly transparent edges and is widely recognized by design tools and browsers. Choose it for logos, icons, and overlays when you do not know what software the reviewer will use. It may produce a larger file than a compressed web format, but that is often a fair trade for a straightforward review.

WebP for web use

WebP can preserve transparency and is useful for websites that accept it. Check with the client before using it for a proofing round, because an older design application or upload system may not handle it. If the file needs to be opened in many different programs, provide a PNG copy as well.

GIF for simple, hard-edged art

GIF transparency is limited to pixels that are fully transparent or fully opaque. It does not handle soft transparency as smoothly as PNG or WebP, so antialiased text, soft shadows, and translucent effects can develop rough edges. Use it only when the artwork and destination suit that limitation.

JPG for a flattened preview

JPG does not retain transparent areas. It is suitable for a reference image with a solid background, not for the transparent artwork itself. If a client asks for a JPG, put the art over the intended background first and make clear that this version is a preview.

TIFF or BMP when the workflow requires it

TIFF is common in some print and imaging workflows, but support for transparency depends on the software and settings used along the way. BMP transparency support is also inconsistent across applications. Confirm the required format with the client, then reopen the exported file in the software used for review. Do not assume that a format name alone guarantees that transparency survived.

How to avoid common proofing problems

1. Keep an untouched master. Save the editable source separately from exported copies. Repeatedly converting a compressed image can reduce quality, and a flattened file cannot recover transparency that has already been removed.
2. Check the source before converting. Look for a transparency indicator or preview the image over a contrasting color. If the background is already solid white, conversion will keep those white pixels.
3. Use the requested dimensions. Ask whether the client wants the original pixel size or a specific delivery size. Avoid shrinking the only copy, especially if the art contains small text or thin lines.
4. Inspect edges at normal size and close up. Zoom in to look for white halos, jagged edges, or stray pixels, then zoom back out to judge how the image will appear in the actual layout.
5. Send the proof in context. Include a separate screenshot or flattened preview over the intended background. This lets reviewers judge placement and contrast without confusing the preview with the transparent source.
6. Confirm the recipient can open it. If you are unsure, provide a PNG for the transparent artwork and a clearly named flattened preview, then ask which format their production workflow needs.
