Settings: Conversion Templates
Configure image conversion with formats, sizing, quality, and watermarking
Overview
Conversion Templates are reusable presets for the Image Conversion process. Each stores an output format and the sizing, quality, colour, metadata, filename, and watermark rules applied when converting images.
This tab lists your presets — built-ins plus any you create. Selecting one shows what it produces.
When to Use
Set up Conversion Templates when the same export keeps coming up and you would rather save the recipe than rebuild it each time. A template bundles every decision behind a conversion — format, size, quality, colour, what happens to metadata, and any watermark — so the Image Conversion process can apply one consistent treatment to a whole collection in a single pass. The convention to save is usually the destination: client deliverables sized and watermarked the way you hand them over, lightweight files for the web, platform-sized exports for social with location data removed, high-resolution wide-gamut files for print, or lossless masters for an archive. Capture each destination once and a shoot can be converted for it the same way every time. The cards below cover the individual choices, and the Managing Templates section covers starting a new preset from a built-in one.
Requirements
- Template name must be 3-40 characters, unique (case-insensitive), and non-empty
- At least one template must exist in the library
- Built-in templates cannot be edited or deleted directly - duplicate them first
- AVIF and JPEG XL output require macOS 15.0 or later
- Sizing dimensions must be 1-30,000 pixels
- Scale percentage must be 1-500%
- DPI must be 1-1200
- Quality settings: JPEG/HEIC/AVIF/JPEG XL 0-100%; PNG and TIFF are lossless (no quality setting)
- Text watermark requires non-empty text when enabled
- Image watermark requires valid file path when enabled
- Watermark opacity must be 0.0-1.0, size percentage must be 1-100%
Template Fields
Each field in the template editor, and how it shapes what the template produces.
The template's name in the Templates list and an optional note describing what it produces.
The format converted images are written in. JPEG, HEIC, AVIF, and JPEG XL are compressed; PNG and TIFF are lossless.
AVIF and JPEG XL output requires macOS 15 or later.
Restricts which input formats this template will convert. Leave it on All Formats to accept any supported image.
How output dimensions are derived, with the pixel or percentage value the chosen mode needs. Original Size leaves dimensions unchanged.
Compression quality, colour space, output DPI, and whether to preserve 16-bit depth. Quality is a percentage and applies only to the compressed formats (JPEG, HEIC, AVIF, JPEG XL); PNG and TIFF are lossless and have no quality control. Colour-space options are Preserve Original, sRGB, Adobe RGB (1998), Display P3, and ProPhoto RGB.
16-bit depth preservation applies only to TIFF or PNG output from a 16-bit source.
What metadata the converted file carries — keep everything, strip everything, or keep or remove specific groups.
Names each converted file from variables and literal text. Available variables include {original}, {width}, {height}, {format}, {quality}, {dpi}, {colorspace}, {date}, and {seq} (zero-padded with {seq:N}).
An optional watermark on the output. A text watermark supports {copyright}, {artist}, {year}, {date}, and {filename}, with a position, font, size, colour, and opacity; an image watermark adds a logo with its own position, size percentage, and opacity.
Managing Templates
Select a template to see its output format, sizing, quality, and the rest of its configuration in the detail panel. A lock icon marks the built-in presets, which are read-only.
Click New, then build the preset from the fields above.
- Click New above the Templates list.
- Name the template and choose an output format.
- Set sizing, quality and colour, metadata handling, and the filename pattern.
- Add a watermark if needed, then save.
Use the buttons beside the list. Edit changes a template you created; the built-in presets are locked, so Duplicate one to get an editable copy. Delete removes a template you no longer need; built-ins cannot be deleted.
Export writes the selected template to a file you can share or back up; Import adds templates from a file. Imported templates arrive as new, editable copies, so importing never overwrites your existing presets.
Tips & Important Notes
- The built-in templates cover common needs: Web Optimized (JPEG 85%, 2048px) is the general-purpose default, Print Ready (TIFF, 300 DPI) suits printing, Social Media (1080px, GPS stripped) protects location privacy, Apple Ecosystem outputs HEIC, and Lossless Web outputs PNG.
- Match the output format to the use: JPEG for web and sharing (smallest files), TIFF for print and archive (lossless), PNG for transparency, HEIC for Apple devices, and AVIF or JPEG XL for newer, more efficient compression (macOS 15.0+).
- JPEG 85% balances quality and size well. Use 90% or more for important images and 75% or less for thumbnails. PNG is lossless, so it has no quality setting to tune.
- Among the sizing modes, Longest Edge constrains the longest side and keeps the aspect ratio, Fit Within Box keeps both sides inside limits, and Percentage scales proportionally.
- Choose a color space for the destination: sRGB for web, Adobe RGB (1998) for print, Display P3 for Apple displays, ProPhoto RGB for archival, and Preserve Original when color accuracy is critical.
- 'Strip GPS Only' removes location while keeping the rest - good for social sharing. Strip All maximizes privacy, and Preserve All suits archives.
- 72 DPI is standard for screens and 300 DPI for print. Use higher values (600+) for fine-art printing or detailed reproductions.
- 'Preserve 16-bit color depth' applies to TIFF and PNG output only. Turn it on when sources are 16-bit (professional cameras, scans) and you need the full color depth.
- Text watermarks accept metadata variables like {copyright}, {artist}, and {year}. Place the watermark in a corner (bottom right is least intrusive) at 50-70% opacity.
- For an image watermark, use a transparent PNG logo at 10-20% of the image width. Keep the position consistent and the opacity low (50-70%) so it does not distract.
- In a filename pattern, {original} keeps the source name. Add {seq:4} for sequential numbering, and literal text like {original}_web to label the output.
