✨ Feature Overview
Implement a reusable file preview system that allows users to inspect uploaded files before performing any processing operation. The feature should support image thumbnails and PDF first-page previews along with displaying basic metadata such as filename, file size, dimensions, and page count.
This enhancement will help users verify that they have selected the correct files before proceeding with operations like conversion, merging, compression, OCR, or background removal.
🚀 Why is this Feature Needed?
Currently, users upload files and directly process them without any confirmation of the uploaded content. This can lead to accidental processing of incorrect files, especially when handling multiple PDFs or images.
Adding a preview layer would:
Improve user confidence before processing.
Reduce user errors and accidental conversions.
Enhance the overall user experience.
Provide reusable UI components that can be integrated across multiple tools.
🔧 Possible Implementation (Optional)
For Images:
Generate preview using URL.createObjectURL()
Display:
Thumbnail
File name
File size
Resolution
For PDFs:
Use PDF.js to render the first page.
Display:
First-page thumbnail
File name
File size
Total page count
This functionality can potentially be reused across multiple tools including:
PDF to PNG
PDF Merge
PDF Split
OCR
Remove Background
Image Compression
Images to PDF
