For custom T-shirt printing, SVG is usually best for logos and simple graphics that need to scale, PNG is usually best for detailed full-color artwork with transparency, and JPG is best only when a rectangular background or photograph is intentional. The correct choice also depends on whether the design will be printed with DTF, screen printing, or embroidered.
This guide explains the difference between PNG, SVG, and JPG files, what each format is good for, and what Same Day Embroidery needs to produce clean custom apparel.
PNG vs SVG vs JPG: which is best for T-shirt printing?
| File type | Best use | Transparency | Can scale without pixelation? |
|---|---|---|---|
| PNG | Full-color DTF artwork, detailed graphics and transparent backgrounds | Yes | No |
| SVG | Logos, lettering, icons and flat-color graphics | Yes | Yes |
| JPG | Photographs or designs with an intentional rectangular background | No | No |
What is a PNG file?
PNG is a raster image format made from pixels. It supports full color and transparency, which makes it a practical choice for detailed DTF graphics that should print without a rectangular background.
When is PNG best for custom shirts?
- Full-color DTF artwork
- Detailed illustrations
- AI-generated designs
- Artwork with a transparent background
- Graphics that contain shading or many colors
A PNG must still have enough pixel resolution for the final print size. A small PNG will become blurry or pixelated when enlarged.
Does every PNG have a transparent background?
No. PNG supports transparency, but it does not guarantee transparency. A PNG can contain a solid white background, a colored rectangle, or even a checkerboard pattern that only looks transparent.
Open the file against both a light and dark background. If a box appears around the design, the background is still present.
What is an SVG file?
SVG is a vector format. Instead of storing the artwork as a fixed grid of pixels, it uses mathematical paths to describe shapes, curves, and colors. A properly created SVG logo can be enlarged for a jacket back or reduced for a left chest without becoming pixelated.
When is SVG best for custom apparel?
- Business logos
- Names and lettering
- Simple icons
- Flat-color graphics
- Artwork that must be produced at several sizes
- Designs that may need color separation or editing
SVG is not automatically better for every design. Complex photographic art, soft textures, or certain AI-generated illustrations may be better delivered as a high-resolution PNG.
Can an AI-generated image be saved as SVG?
Saving a pixel image with an SVG extension does not automatically turn it into true vector artwork. The design must be rebuilt or accurately traced into vector paths. Automatic tracing can introduce rough edges, excessive anchor points, missing details, and distorted lettering.
Simple AI-generated logos are easier to convert into clean vectors than detailed illustrations.
What is a JPG file?
JPG is a compressed raster image format commonly used for photographs. It does not support transparent backgrounds, so the entire rectangular canvas remains part of the file.
When is JPG acceptable for shirt printing?
- The artwork is a photograph
- The rectangular background is part of the design
- The file is high resolution at the intended print size
- No transparent areas are needed
A JPG is usually not the best choice for a logo that should appear directly on the garment without a visible box.
Why does my JPG print with a white box?
JPG files cannot store transparency. If the design appears on a white canvas, that white area is part of the image and may print as a rectangle. The background must be removed and the cleaned artwork exported as a transparent PNG or rebuilt as a vector file.
What is the difference between raster and vector artwork?
PNG and JPG are raster formats composed of pixels. SVG is a vector format composed of paths.
- Raster: Resolution-dependent. Enlarging beyond the original size can reveal pixels and blur edges.
- Vector: Resolution-independent. Shapes and lettering can scale without pixelation when they are built as true vector paths.
Neither category is always superior. Photographic and heavily textured artwork fits raster formats, while logos and flat graphics benefit from vector construction.
What file is best for DTF printing?
For most detailed full-color DTF transfers, send a high-resolution transparent PNG at the intended print size. A clean SVG is excellent for flat logos and graphics, especially when the printer needs to resize or edit colors.

What file is best for embroidery?
SVG, EPS, AI, or vector PDF files are strong source files for embroidery logos because their shapes are easy to identify and edit. However, none of these is the final machine file.
The artwork still needs embroidery digitizing, which converts the visual design into stitch types, directions, densities, underlay, trims, and color sequences.

What about PDF, EPS and AI files?
PDF, EPS and Adobe Illustrator files can contain vector artwork, raster artwork, or both. The extension alone does not prove that a file is vector. A low-resolution JPG placed inside a PDF is still a low-resolution raster image.
Your print shop can inspect whether the shapes and lettering are true vectors.
Does 300 DPI make a file print-ready?
Not by itself. Changing the DPI setting does not add missing detail to a small image. Actual pixel dimensions, edge quality, compression and the intended physical print size all matter.
For example, a tiny image labeled 300 DPI can still look blurry when printed across the back of a shirt.
How do I export a design from Canva for shirt printing?
For detailed DTF artwork, export a PNG at the largest practical size and enable transparent background when your Canva plan and design allow it. For simple logos, PDF Print or SVG may provide a better source, but confirm that the artwork remains editable and that fonts or effects have not changed.
Always inspect the exported file rather than relying only on the design preview.
How do I export AI-generated artwork?
Download the original full-resolution result from the image platform. Avoid screenshots and compressed images from social media or text messages. Correct the spelling, remove unwanted backgrounds, clean stray pixels, and preserve an untouched copy of the original.
For stronger source artwork, use our best AI prompts for T-shirt designs.
What should I send my print shop?
- The original highest-resolution artwork
- Any available vector source file
- The garment color
- Print or embroidery placement
- Desired finished width or height
- Quantity
- Deadline
- Exact spelling of all text
Frequently asked questions
Is PNG or JPG better for DTF printing?
PNG is usually better when transparency is required. JPG can work for photographs or designs with an intentional rectangular background.
Is SVG always the best file?
No. SVG is excellent for logos and flat graphics, but high-resolution PNG is often more practical for complex full-color illustrations and photographic effects.
Can I convert JPG to PNG?
Yes, but changing the extension does not remove the background or restore lost resolution. The artwork still needs cleanup.
Can I print a low-resolution logo?
It may be printable at a small size, but enlarging it can expose blur and pixelation. A redraw or true vector version may be needed.
Is a PDF automatically vector?
No. A PDF can contain vectors, raster images, or both. The contents must be inspected.
Can Same Day Embroidery check my artwork?
Yes. Same Day Embroidery can review the file type, resolution, transparency, edges, colors and intended size before production.
