When uploading Photoshop (PSD) files into Bannersnack, there are two things you need to know:
Basic requirements and optimizations to prepare your files correctly.
Limitations to be aware of when importing, since not all Photoshop features are supported.
Basic Requirements & Optimizations
Area | Best Practice | Notes / Recommendation |
File size & artboard | Max file size: 100 MB | Scale or split PSDs if they exceed these limits. |
Export note | PSD files can be imported into Bannersnack but cannot be exported back out | Keep a working copy in Photoshop for future edits. |
Layout setup | Use a square layout (1:1 aspect ratio) when possible | Square layouts are easier to adapt to multiple ad formats. |
Design size | Match your PSD size to the largest ad size you plan to create | Oversized files may slow performance without adding value. |
Hidden layers | Remove hidden layers before import | Bannersnack ignores hidden layers. |
Organizing layers | Group related layers (e.g., text, buttons, logos)
| Reduces file size and ensures better resize logic. |
Fonts | Upload any custom fonts to Bannersnack before import | Missing fonts trigger warnings during import. |
Limitations
Area | Limitation | Notes / Workarounds |
Layer effects & styling | Effects (e.g., shadows, glows) must be rasterized before import | Photoshop supports live effects, but rasterizing preserves them in Bannersnack. |
Blending & transparency | Blend modes (e.g., Multiply, Overlay) are not supported | Flatten, merge or raserize layers with blending. |
Rotation | Only text layers retain rotation | Other rotated layers revert to default orientation. |
Text options | Auto leading, horizontal/vertical scaling, and tight letter spacing (tracking) are not supported | Adjust text in Photoshop before import. |
Missing fonts | A yellow triangle signals a missing font in Bannersnack | Upload the font prior to importing your PSD. |
Graphics & vector assets | SVGs convert to PNGs | Rasterize SVG layers before import. |
Color & bit depth | Only 8-bit color mode is supported | Convert PSDs before upload. |
Color profiles | Use sRGB for consistency | Other profiles may cause color shifts. |
Note: Most of these limitations are related to Bannersnack’s import process, not Photoshop itself. Always keep your original PSD in Photoshop for full editing capability and work on a duplicate.
