PicPrune Form Uploads

Description

PicPrune Form Uploads helps WordPress sites handle large image uploads submitted through forms.

Visitors often upload full-size phone photos. These files can make notification emails heavy, fill mailboxes, slow down manual review, and consume unnecessary storage. This plugin optimizes uploaded images server-side during WordPress upload handling and before Contact Form 7 sends email attachments.

Features

  • Compress JPEG, PNG, and WebP uploads.
  • Convert HEIC/HEIF files to JPG when the server supports it.
  • Resize large images to configurable maximum dimensions.
  • Optimize Contact Form 7 temporary uploads before mail delivery.
  • Optimize image uploads from Drag and Drop Multiple File Upload for Contact Form 7 before mail delivery.
  • Replace converted HEIC/HEIF Contact Form 7 attachments with JPG files.
  • Skip small files below a configurable threshold.
  • Keep the original when optimization would make a file larger.
  • Settings page under Settings > PicPrune Form Uploads.

Example use cases

  • Quote request forms with photo uploads.
  • Support forms with screenshots or product photos.
  • Application, registration, and booking forms.
  • Inspection, reporting, or documentation forms.
  • Any Contact Form 7 form where users upload images.

HEIC / HEIF support

HEIC/HEIF conversion requires the PHP Imagick extension and an ImageMagick build with HEIC or HEIF decoding support. If this support is unavailable, the plugin leaves HEIC/HEIF files unchanged and shows a warning on the settings page. JPEG, PNG, and WebP optimization can still work through standard WordPress image editing support.

Third-party plugin compatibility

This plugin includes compatibility for Contact Form 7 and Drag and Drop Multiple File Upload for Contact Form 7. It is an independent plugin and is not affiliated with or endorsed by those projects.

FAQ

Does this work with Contact Form 7?

Yes. The plugin includes explicit Contact Form 7 hooks to process temporary upload files before mail is sent.

Does this work with HEIC photos from iPhones?

Yes, if the server has PHP Imagick and ImageMagick with HEIC/HEIF decoding support. The settings page warns you if that support is unavailable.

Does this convert every image to JPG?

No. JPEG, PNG, and WebP files stay in their original format and are compressed/resized. HEIC and HEIF files are converted to JPG.

Does this change already uploaded files?

No. It only processes new uploads after activation.

Does this optimize images in the visitor’s browser before upload?

No. Optimization happens server-side during WordPress or Contact Form 7 upload handling.

Will this work with every form plugin?

It works with standard WordPress upload handling and has specific support for Contact Form 7. Other form plugins may work if they use the standard WordPress upload pipeline. Plugin-specific integrations can be added later.
