To preserve noise texture in Affinity exports on a Mac, check the artwork at 100%, export at the intended dimensions, and allow rasterization where the format requires it. Affinity’s documented controls vary by file format.

This guide covers exporting artwork that already contains noise, using the current Affinity desktop app. The task is to keep the visible texture in the delivered file. The documentation does not promise that an exported file will retain Affinity’s editable noise controls.

Check which noise effect your artwork uses

Affinity offers noise as a color attribute and through the Add Noise filter. Identifying the source helps you adjust the existing artwork without accidentally introducing a different texture.

For noise applied to a fill or stroke, select the object and open Window > General > Color. The Color panel includes an opacity/noise switch and a shared control for those attributes. Confirm that you are inspecting the appropriate fill or stroke. Color panel — Affinity.

The Add Noise filter is a separate operation that introduces random pixels. Its documented controls are Intensity, Monochromatic, and Uniform or Gaussian distribution. It is available as a destructive filter and as a non-destructive live filter. These settings describe how the texture is generated; they are not export settings. Add Noise filter — Affinity.

Keep your editable Affinity document as the working master while testing exports. If you need to change the texture later, make that change in the master and export again. Treat the delivered image or PDF as an output to inspect, rather than assuming it preserves the original effect’s editing options.

Establish a useful comparison before changing export settings

Press Command–1 to view the document at 100%. Affinity documents this as the magnification where document pixels map directly to screen pixels. Choose a small textured region that you can find again in the exported file. A plain rectangle with a noisy fill is a useful neutral test if the complete design makes comparison difficult. Zooming — Affinity.

Check that region at both 100% and the intended viewing size. These observations answer different questions: whether the file contains visible pixel detail, and whether that detail is noticeable when the artwork is displayed as intended. Changing magnification is an inspection step; it does not instruct the exporter to preserve a particular on-screen appearance.

For diagnosis, use the full Export dialog. Affinity documents it as providing all supported export formats and settings, together with a preview. Quick Export uses presets and a smaller set of controls, while the Slice Studio handles multiple outputs. Starting with one export makes it easier to identify which change affects the result. About exporting — Affinity.

Export a PNG to check the texture at its intended dimensions

For a screen image, start with a PNG export at the dimensions you actually need. This gives you a concrete file to compare before investigating PDF or SVG behavior.

  1. Choose File > Export > Export in the current desktop app.
  2. Select a PNG preset.
  3. Set Area to the intended document, page, or named artboard. If the noise is on a separate overlapping layer, remember that Selection Only excludes other layers, while Selection Area includes overlapping content.
  4. Check the output Width and Height, keeping the aspect ratio locked unless a deliberate change is required.
  5. Inspect the preview, select Ask for Location, and click Export. Name the file and click Save. Export dialog and Export Settings — Affinity.

PNG does not have the documented Rasterize selector used for PDF, SVG and EPS. Looking for “Rasterize Everything” in PNG settings will therefore send you toward a control that is unavailable for that format. PNG does offer Palettized output, which maps the image to a color palette; leave that disabled for an initial texture comparison so palette reduction is not another variable. Export Settings — Affinity.

Open the saved PNG in Affinity and inspect the same region at 100%. Then view it at the size at which it will be used. Record whether the texture is present, faint, or absent. Avoid changing the noise strength, dimensions, and export format simultaneously: otherwise, an improvement will not tell you which change helped.

For example, suppose an illustrative design is 2400 pixels wide but the required output is 1200 pixels wide. Export one PNG at each width with the other settings unchanged. If the larger file retains the desired appearance and the smaller one does not, the comparison identifies output scaling as a variable to investigate. It does not establish an Affinity defect or prove that a particular resampling method will restore the texture.

Preserve the appearance in PDF, SVG or EPS

For PDF, SVG and EPS, Affinity explicitly documents three Rasterize choices. Their consequences matter when the artwork contains properties the selected format cannot represent directly. Export Settings — Affinity.

Rasterize choice Documented behavior Practical use for this task
Nothing Unsupported elements are omitted instead of rasterized. Avoid this when preserving an unsupported effect’s appearance is necessary.
Unsupported properties Only unsupported elements are rasterized. Start here when you want to retain supported vector content.
Everything All elements are rasterized to reproduce the design’s appearance. Use as an appearance-focused alternative when a fully rasterized result is acceptable.

Start with Unsupported properties, export, and inspect the result. If the appearance remains unsuitable, compare an export using Everything. This is a supported path for rendering the artwork into pixels within the chosen output format; it does not preserve a fully editable vector construction.

Also check Raster DPI, which controls the resolution of effects rasterized during export. Use document resolution follows the project’s DPI. For the first comparison, disable Downsample images and Allow JPEG compression to remove those two processing choices from the test. These controls apply to PDF, SVG and EPS, rather than PNG. Export Settings — Affinity.

A PDF preset is only a starting point. Affinity’s preset comparison shows that PDF (digital - small size) uses 72 Raster DPI, while PDF (digital - high quality) uses 300. PDF (flatten) rasterizes everything, uses document resolution, and disables downsampling, but still enables JPEG compression. Selecting “flatten” therefore does not remove every setting worth checking. Compare PDF export presets — Affinity.

There is no noise-specific export preservation switch documented in the Export Settings reference. Its general rasterization contract supports preserving appearance, but does not promise an editable vector equivalent for Affinity noise. If your delivery requires exclusively vector elements, these documented controls do not establish a way to meet that requirement while retaining the same noise texture.

Use the exported result to choose your next change

The following diagnostic sequence is an editorial decision aid derived from the documented controls. It is not a claim that one setting fixes every noise-export problem.

What you observe Next useful check
A separate texture layer disappears Check Area and whether Selection Only excluded it.
PNG looks acceptable, but PDF or SVG loses the effect Check Rasterize; compare Unsupported properties with Everything.
Texture is visible at native dimensions but weak in a smaller export Compare output dimensions while holding other settings constant.
PDF texture changes between presets Compare Raster DPI, downsampling and JPEG compression.
Texture is visible at 100% but weak at the intended viewing size Adjust the source texture for that delivery size, then export again.

If you need to adjust the artwork, return to the control that created its noise. Use the Color panel’s noise control for color noise, or Intensity for Add Noise. A live Add Noise filter permits non-destructive adjustment. Neither the Color panel documentation nor the Add Noise settings list provides a dedicated grain-size control, so do not build the export process around an assumed one. Color panel and Add Noise filter — Affinity.

Once the saved file has the texture you want at the intended dimensions, retain that file alongside the editable master and note its export settings. The useful stopping point is a verified output: visible noise at the required viewing size, with any rasterization accepted as part of the delivery.
