How to Prepare a Design File for Printing: PDF, JPEG and PNG Guide

A design can look sharp on a phone or laptop and still print badly. Screens hide problems such as low resolution, missing bleed, tiny text and incorrect final size.

This guide explains how to prepare a print-ready file for Waaprint before you order. It applies to business cards, flyers, brochures, banners, stickers, packaging, apparel artwork and most other print products.

What is a print-ready file?

A print-ready file is artwork prepared at the correct final size and quality for physical printing. It should contain the correct text, images, colours and layout, with enough space around the edges for trimming.

A good print-ready file helps us produce your work accurately and reduces avoidable delays.

Best file formats for printing

PDF: usually the best option

PDF is usually the preferred format for flyers, business cards, brochures, menus, invitations, letterheads and other page-based artwork.

It preserves the layout more reliably than a screenshot or social-media export. If you created your design in Canva, Adobe Illustrator, CorelDRAW or Photoshop, export a high-quality print PDF where possible.

Before sending a PDF, check that:

• The final size is correct
• Important text is not too close to the edge
• Images are sharp at the required size
• The file contains all pages you want printed
• The version you send is the final approved version

JPEG or JPG: suitable for high-resolution artwork

A high-resolution JPEG is useful for artwork that is already one flat image, such as a poster, social-media-style flyer or photo-based design.

JPEG files are not ideal if you still need to edit text later. Once the file is exported, the text and images are combined into one image.

Use a JPEG only when it is large enough for the final print size. A small WhatsApp image or screenshot may look acceptable on your phone but can look soft or pixelated in print.

PNG: useful for high-quality image artwork

PNG can be a good option for high-resolution artwork, especially where sharp graphics or transparent backgrounds matter. It is commonly used for logos, artwork for apparel and design files with clean edges.

For page designs such as brochures or multi-page documents, PDF is usually more practical.

SVG: useful for logos and vector artwork

SVG files are useful for logos, icons and other vector designs because they can scale without losing sharpness. If you have your logo in SVG format, send it along with the complete artwork when relevant.

Use the correct final print size

Your file should match the size you want printed.

For example:

• Standard business card: 90 mm × 55 mm
• A5 flyer: 148 mm × 210 mm
• A4 flyer or letterhead: 210 mm × 297 mm
• Banner or sticker: use the exact width and height requested

Do not design a business card at A4 size and expect it to be reduced perfectly. Text can become too small and image quality can change.

If your job has a custom size, include the required width and height when you request a quote.

Use Waaprint's free Print-Ready File Checker to compare your file against common print specifications before you order.

Resolution: why 300 DPI matters

Resolution describes how much image detail is available for printing. For small printed items such as business cards, flyers and stickers, 300 DPI at the final print size is a good target.

Low-resolution images can print blurry, rough or pixelated.

A few practical rules:

• Do not use a screenshot of a logo if you have the original file.
• Do not stretch a small image to fit a large banner.
• Do not download an image from WhatsApp and assume it is print quality.
• Ask for the original high-resolution artwork when a client gives you only a compressed image.

Large-format prints may use different effective-resolution requirements depending on their size and viewing distance. A banner viewed from several metres away does not need the same resolution as a business card viewed up close.

Add bleed to designs that reach the edge

Bleed is extra artwork that extends beyond the final trim edge. It helps avoid unwanted white lines when the printed sheet is cut.

For many printed items, use 3 mm bleed on every side unless the product specification says otherwise.

Example: if your finished flyer is A5, the background image or colour should extend beyond the final A5 edge. Do not stop a full background exactly at the trim line.

Bleed is particularly important for:

• Business cards
• Flyers
• Brochures
• Invitations
• Thank you cards
• Stickers
• Posters
• Packaging artwork

Keep text and logos inside a safe margin

Do not place important text, phone numbers, QR codes, logos or faces too close to the edge.

Keep them inside a safe margin so a normal cutting variation does not trim away important content. Around 3 to 5 mm inside the final edge is a useful starting point for many small printed products.

For banners, allow enough clear space near eyelets or finishing points.

Check spelling and phone numbers before sending

Printing reproduces what is in the approved file. Before you send the final artwork, check:

• Business name
• Phone numbers
• Website and social handles
• Date and venue
• Price and offer details
• QR-code destination
• Names on certificates, invitations or ID cards
• Spelling and punctuation

Read the file at 100% zoom and ask someone else to check it too. This is one of the easiest ways to avoid a costly reprint.

Prepare AI-generated designs for printing

AI-generated designs are accepted. However, they still need to meet normal print requirements.

Before sending an AI design:

1. Check all text carefully. AI images can produce incorrect or unreadable lettering.
2. Make sure the image is high resolution at the intended print size.
3. Replace any fake logos, contact details or QR codes with the correct versions.
4. Use a print-ready PDF or high-resolution JPEG/PNG.
5. Tell Waaprint the intended product and final size.

If you used AI only for an illustration or background, place it into a proper flyer, card, banner or packaging layout before exporting the final print file.

Which file should I send for common products?

Business cards

Send a two-page PDF for front and back, or clearly labelled front and back image files. Use the correct card size, include bleed and keep critical information inside the safe margin.

See Business Card Printing options.

Flyers and handbills

A print PDF is preferred. Make sure the file matches the selected size, such as A5 or A4, and use high-resolution images.

See Flyer and Handbill Printing options.

Banners and backdrops

Send artwork at the correct proportional size. Include the final width and height, and avoid low-resolution images stretched across a large area.

See Flex Banner Printing options.

Branded T-shirts and apparel

Use a transparent PNG or a high-quality print file for the artwork when possible. State the intended print position and garment colour, especially if the design includes white or light elements.

See T-Shirt Printing options.

Stickers and labels

State the final label size and shape. Use vector artwork or high-resolution PNG/PDF files for logos and text so the small details remain clear.

See Transparent Sticker Printing options.

Frequently asked questions

Can Waaprint print a JPEG file?

Yes, provided it is high resolution at the final print size. For page-based designs, PDF is often a better choice.

Can Waaprint print AI-generated designs?

Yes. Send a print-ready PDF or high-resolution JPEG/PNG. AI-generated designs are accepted and receive a free design review.

What happens if my file is not print-ready?

Waaprint will explain the issue during the free design review. You may need to resend the file, adjust the design or request design support before printing begins.

Do I need to add bleed?

For artwork that has colour or images extending to the edge, yes. Use 3 mm bleed unless the product specification states otherwise.

Can I send a WhatsApp image for printing?

You can send it for review, but WhatsApp often compresses images. The original file, print PDF or high-resolution JPEG/PNG is safer for quality printing.
