Flattening is an export decision, not a substitute for a clean label master. It may be useful when a recipient needs a fixed visual result, but it changes the structure of the PDF. Before choosing it, find out what the printer expects and keep the source design available for future scent or size changes.
01
Understand what the flattened export contains
A Canva design may contain separate text, shapes and images. Canva describes its flattened PDF as merging those elements into one image. Do not assume that the resulting text and vector shapes remain independently editable or retain their original structure simply because the downloaded file still has a PDF extension.
For an illustrative candle label, the brand name, scent, decorative border and background become part of that merged output. The Canva master remains the place to change the scent wording. Keep a clearly named editable version and treat the flattened file as a particular delivery format for an approved design.
02
Ask what the recipient needs before selecting the option
A printer may request a particular PDF standard, image resolution, bleed treatment or other production setting. Ask whether flattening is appropriate for its workflow. Some recipients need preserved text or vector artwork, so a fixed-looking file is not automatically the best production file for every printing process.
If you are troubleshooting a visible export problem, save both the unflattened and flattened versions with distinct filenames. Compare the exact affected element rather than changing several settings at once. Send the version the provider approves, with the intended finished dimensions stated separately in the order notes.
03
Keep flattening separate from compression
Compression aims to reduce file size and can lower image quality. Flattening changes how the design’s elements are represented. One option does not answer the same question as the other. A smaller download is not evidence that a label will print more accurately or that its fine text has been preserved.
Consider a small tin label with thin lettering. If a flattened export is requested, inspect the saved result for soft edges at the physical output size. Do not turn on compression merely because flattening has been selected. Review every additional export setting against the provider’s requirements and account availability.
| Version | Purpose to consider |
|---|---|
| Editable Canva master | Future wording, layout and variant changes |
| Unflattened PDF | Recipient workflow requiring preserved structure |
| Flattened PDF | Approved fixed image-based delivery when suitable |
04
Check accessibility and production approval
Flattened text becomes part of an image, which matters if the PDF is also a customer-facing digital document. Canva’s PDF accessibility guidance tells users to leave Flatten PDF unchecked for accessible output. Keep a suitable accessible digital version when needed instead of using the production export for every purpose.
Open the final saved file and check the page count, dimensions, scent wording and small text. Print a proof or request the provider’s proof before the full run. Archive the approved export with a note that it was flattened so a later editor does not mistake it for an editable source.
BEFORE YOUR NEXT STEP
Your practical checklist
- Keep the editable Canva master.
- Confirm the printer’s preferred file structure.
- Review flattening and compression separately.
- Inspect small text and approve a proof.
Questions & answers
Will flattening keep all text as selectable text?+
Canva describes flattening as merging design elements into an image. Do not rely on it for selectable text or an accessible digital PDF.
Should every label PDF be flattened?+
No. Use the format and settings appropriate for the recipient’s printing workflow. Ask the provider when its specification does not address flattening.
