Image Optimizer
Image Optimizer
Recompresses oversized original image attachments (image_1920 and image_variant_1920 by default) to reclaim filestore space.
For each targeted image the module:
- downscales it to a maximum side of max_dim pixels (default 1920);
- re-encodes photos without transparency as progressive JPEG at the configured quality (default 85);
- keeps images with transparency as optimized PNG (alpha preserved);
- skips animated GIFs (never flattens the animation);
- keeps the result only when it is actually smaller.
The optimized image is written back through the owning record, so Odoo regenerates the resized variants (image_1024/512/256/128) from the new, smaller original.
Processed attachments are flagged (deltatech_image_optimized) and skipped on the next run. Because Odoo creates a fresh attachment whenever an image field is updated, newly uploaded or changed images are picked up automatically.
Configuration
System Parameters (Settings → Technical → System Parameters):
| Key | Default | Meaning |
|---|---|---|
| deltatech_image_optimize.quality | 85 | JPEG quality (1..95) |
| deltatech_image_optimize.max_dim | 1920 | max side in pixels |
| deltatech_image_optimize.min_size | 102400 | only images larger than this (bytes) |
| deltatech_image_optimize.batch | 1000 | images per cron run |
| deltatech_image_optimize.target_fields | image_1920,image_variant_1920 | fields to optimize |
Scheduled action
Image Optimizer: recompress oversized images runs daily. It is disabled by default — review the configuration, test on staging, then enable it.
For a large one-time backlog you can loop the batch method from the shell:
while env["ir.attachment"]._dt_image_optimize_run(limit=2000)["scanned"]: env.cr.commit()

- Initial release.
- Add ir.attachment.deltatech_image_optimized marker field.
- Recompress original image attachments (image_1920 / image_variant_1920): downscale to max_dim, JPEG (quality tuned) for opaque images, optimized PNG for images with alpha, skip animated GIFs.
- Write the optimized image back through the owning record so Odoo regenerates the resized variants from the smaller original.
- Configurable via ir.config_parameter (quality, max_dim, min_size, batch, target_fields).
- Daily scheduled action Image Optimizer: recompress oversized images, disabled by default.
