“Fast. Simple. Reliable file transformation for everyday tasks.”
The File Convert feature is one of the core modules of EzKito and represents the foundation of the platform’s philosophy: simplifying everyday digital tasks that are repetitive, inconvenient, or scattered across too many tools. Whether it’s converting images into PDFs, transforming documents, extracting individual pages, or generating quick one-off formats, EzKito offers a clean, unified interface that makes these tasks effortless.
What Is the File Convert Feature?
The File Convert module was designed to solve a common frustration:
simple file transformations often require switching between multiple websites, downloading temporary utilities, or dealing with ads, limits, and watermarks. EzKito focuses on providing an all-in-one, ad-free, reliable conversion experience that works directly inside the browser.
Currently, the module supports conversions across image formats, PDF generation, document exports, and PDF-to-image transformations. All conversions run through a whitelist-based validation system to guarantee reliability and prevent invalid format combinations.
Supported Conversions
EzKito currently supports the following transformation flows:
Image → Image
•
PNG JPG
JPG•
PNG JPEG
JPEG•
JPG PNG
PNG•
JPEG PNG
PNGImage → PDF
•
PNG → PDF
•
JPG → PDF
•
JPEG → PDF
Document → PDF
•
DOCX → PDF
•
PPTX → PDF
•
XLSX → PDF
•
TXT → PDF
PDF → Image
•
PDF → PNG
•
PDF → JPG
•
PDF → JPEG
These pairs represent the most practical conversions users typically need, without overwhelming them with unnecessary or unreliable options.
Smart Validation System
To prevent user mistakes, EzKito applies two layers of validation:
1.
Frontend validation
Invalid output formats do not appear in the dropdown at all.
2.
Backend validation
Even if the user bypasses the UI, unsupported conversions are rejected safely using a strict conversion whitelist.
This dual-layer approach ensures that EzKito remains stable, predictable, and resistant to malformed input.
Image → PDF Output Modes: Merge or Separate
One of the most important features of EzKito is the ability to control how image files are exported into PDF format. When uploading multiple images, users can choose between two output modes:
Merge into one PDF
All images are combined into a single multi-page PDF.
This is ideal for documents, reports, and organized bundles.
Create separate PDFs (ZIP)
Each image becomes a separate one-page PDF.
If multiple images are uploaded, the PDFs are packaged into a ZIP archive.
The default option is Merge, ensuring that new users experience the simplest workflow first.
Output Filename Rules
To keep files organized, EzKito names outputs using intuitive rules based on the first uploaded file:
Scenario | Output Filename |
1 image + merge | original_ezkito.pdf |
multiple images + merge | original_merged_ezkito.pdf |
1 image + separate | original_ezkito.pdf |
multiple images + separate | original_separated_ezkito.zip |
This makes it easy to identify the content and conversion mode at a glance.
Technical Architecture
The File Convert module is built with:
Django (Backend)
•
Handles format validation
•
Manages uploaded files
•
Executes conversions
•
Generates FileResponse downloads
Pillow (PIL)
•
Opens, decodes, and processes images
•
Converts images to RGB
•
Saves images as PDFs
•
Builds multi-page PDF documents
Python Zipfile
•
Packages multiple PDFs into a ZIP archive for the “separate” mode
JavaScript (Frontend)
•
Dynamically filters available output formats
•
Shows/hides the PDF Output Mode section
•
Maintains a smooth user experience
This stack ensures fast performance, secure processing, and clean extensibility for future enhancements.
How Conversion Works (Code Samples)
Below are simplified versions of the actual conversion logic used by EzKito.
Merging Multiple Images into One PDF
def _merge_images_into_single_pdf(files):
images = [_open_image_from_uploaded(f) for f in files]
buffer = io.BytesIO()
first, *rest = images
if rest:
first.save(buffer, format="PDF", save_all=True, append_images=rest)
else:
first.save(buffer, format="PDF")
buffer.seek(0)
return buffer
Python

Creating Separate PDFs and Packaging as ZIP
def _convert_images_to_separate_pdfs_zip(files):
zip_buffer = io.BytesIO()
with zipfile.ZipFile(zip_buffer, "w", zipfile.ZIP_DEFLATED) as zip_file:
for f in files:
img = _open_image_from_uploaded(f)
pdf_bytes = io.BytesIO()
img.save(pdf_bytes, format="PDF")
pdf_bytes.seek(0)
base_name = f.name.rsplit(".", 1)[0]
pdf_filename = f"{base_name}_ezkito.pdf"
zip_file.writestr(pdf_filename, pdf_bytes.read())
zip_buffer.seek(0)
return zip_buffer

Single Image → PDF
def _single_image_to_pdf(f):
img = _open_image_from_uploaded(f)
buffer = io.BytesIO()
img.save(buffer, format="PDF")
buffer.seek(0)
return buffer

Future Plans
The File Convert module will continue expanding over time. Planned enhancements include:
•
Full document conversion support (DOCX/PPTX/XLSX → PDF rendering)
•
High-resolution PDF → image conversion
•
Image compression and resizing
•
PDF splitting and merging
•
OCR-based text extraction
•
Drag-and-drop upload support
•
Bulk workflow presets
•
Faster processing for large batches
EzKito aims to evolve into a comprehensive, everyday digital utility hub that users can rely on for nearly any file-related task.
Conclusion
The File Convert module is more than just a converter—it’s a productivity tool designed to save time, reduce friction, and streamline routine digital tasks.
With intuitive controls, smart defaults, and a robust backend, EzKito delivers a reliable file transformation experience while remaining fast and easy to use.
As new modules such as YouTube Download, Document Summary, and AI-powered utilities join the platform, EzKito will continue growing into a complete ecosystem for everyday digital work.
