Desktop build notes

Read the founder note on why the desktop app stayed registered-only, what changed in the launch plan, and how the build path evolved.

Target file sizes

Set a target such as 500KB and let the workflow search for the best quality that fits.

Saved workflows

Save a Shopify, website, or client export workflow and rerun the same rules next time.

Local privacy

Process source images on your machine and strip metadata by default.

Delivery reports

Export JSON and CSV reports with total savings, failed outputs, and target-size pass/fail results.

Supported jobs

Built around practical site work.

  • Convert large PNG screenshots to delivery-friendly WebP copies.
  • Prepare product image sets with consistent dimensions and naming.
  • Try to keep WebP, JPG, and AVIF exports under a target KB size.
  • Save reusable workflows for repeat store, website, and client jobs.
  • Create SEO-safe filenames with lowercasing, slug cleanup, and sequence numbers.
  • Generate JSON and CSV reports with totals, savings, and target-size results.
  • Keep original files separate from optimized website exports.
  • Export WebP, JPEG, PNG, or AVIF copies through a local Sharp workflow.
  • Use presets for Shopify, WooCommerce, WordPress, SaaS landing pages, and social previews.

Example workflow

Compress a whole folder toward 500KB outputs.

node src/convert.mjs --preset shopify --target-kb 500 --slugify-filenames true --number-files true --save-workflow shopify-500kb

The workflow can be rerun later with node src/convert.mjs --workflow shopify-500kb. Reports record total savings, output bytes, selected quality, target bytes, and whether each file met the target.

FAQ

What formats does it support?

The desktop beta workflow supports PNG, JPG/JPEG, WebP, and AVIF outputs through the local Sharp engine.

Can it target a file size such as 500KB?

Yes. The desktop beta workflow supports target-size compression for WebP, JPG, and AVIF exports, plus saved workflows for repeat jobs.
