Implement client-side conversion and optimization of images (including HEIC) before AJAX submission to

Budget: 70 USD Deadline: 2 days

Hello! The task is clear and right in my zone — clean client-side JS, I won't touch the PHP core of Tamaranga.

Here's how I'll do it:
• Intercept file selection before AJAX (change on input[type=file] / hook of your uploader).
• Determine format by MIME + extension (not just by name).
• HEIC/HEIF → JPEG via heic2any.
• AVIF, WebP, JFIF, TIFF, BMP, and heavy PNG/JPEG (>3-5 MB) → recompress via HTML5 Canvas to 1920px on the long side, quality 0.85.
• Wrap the result in new File() with .jpg and substitute it in FormData INSTEAD of the original — all field names, array structures, and AJAX parameters will be preserved exactly so that the engine accepts it as a regular JPEG and generates a preview itself.
• Promise queue — conversion strictly one photo at a time, the smartphone browser won't freeze on 5-10 photos.
• Loader "Optimizing photo..." + spinner during conversion.

First, I will create an isolated test on an empty HTML page with this form — I will show that it works; after your OK, I will transfer it to the Tamaranga template.

Deadline is 2 days, through a Secure Deal, starting today. I have a couple of clarifications regarding your AJAX uploader — I will send them in a private message at the start. Expand

Hanbi, the task is clear: we need to intercept the file selection before AJAX, keep the structure of the Tamara fields, and replace the sources with JPEG-Blob/new File() without modifying PHP. I will implement HEIC/HEIF conversion using heic2any, and heavy PNG/WebP/JPEG files through Canvas with a queue to avoid browser freezing. I have already done client-side upload processing and integration with AJAX uploaders. First, I will create an isolated test on a blank page, then carefully transfer it to the template.

Hello. I did the following: intercepting photo uploads, converting HEIC using heic2any, resizing on Canvas, and replacing Blob in FormData without modifying the PHP core. First, I will show a working test on a blank page, then I will transfer it to Tamaranga.

⚙️ Client-side HEIC conversion right before sending is the right approach: we change nothing in the PHP core of Tamaranga, everything is done in the browser before AJAX.

I will do the following:

- Intercept the change event on input[type=file]
- Convert HEIC to JPEG-Blob using heic2any
- Optimize images through Canvas — compress to the required sizes without significant loss of quality
- Replace original files with new File() objects, keeping the structure of Tamaranga's fields intact

I have experience with this: I did client-side image optimization for AJAX upload forms — after the changes, file sizes dropped by 3-5 times, and server load decreased significantly.

Result: users get fast uploads even from iPhone, and your server does not perform unnecessary work.

I can start immediately — just write to me, and I will draft a plan for the first stage in 10 minutes. Expand

Hello!

The task is clear, it’s exactly my area, I won’t touch the PHP core, only client-side JS. Here’s what I will do:

- Intercept file selection in the AJAX uploader (change on input[type=file] / uploader hook)
- Determine by MIME type and extension, not just by extension
- HEIC/HEIF: convert via heic2any to JPEG
- Large PNG/WebP/JPEG (more than 3-5 MB): reduce to 1920px on the long side, quality 0.85, using HTML5 Canvas
- AVIF/BMP: re-encode via Canvas where the browser decodes them natively
- Wrap each result in new File() with .jpg and insert into FormData, preserving all original field names, array structures, and AJAX parameters exactly as they are, so the engine accepts it as a regular JPEG and generates a preview
- Promise queue: conversion strictly in order, so a batch of 5-10 photos doesn’t hang the phone browser
- Loader: spinner "Optimizing photo..." during conversion

Honest point: TIFF (and part of JFIF) the browser does not decode via Canvas natively, so I will add a lightweight decoder (like UTIF) as a fallback, otherwise they will quietly not convert. I will specify exactly which formats are covered.

I will first provide a separate empty HTML page with an upload form for testing, after verification I will transfer it to the Tamaranga template.

One question: should I convert AVIF and BMP too, or only those formats that currently do not pass (HEIC, TIFF, JFIF)?

Hello! 🔥 The task is absolutely clear, and I can clearly see how to implement this client preprocessing without interfering with the closed PHP core of Tamaranga v2. I have ready experience solving similar tasks with streaming image optimization (you can check out my concept of the JPEG conversion queue on GitHub: https://github.com/ShuveeDev/ImageConverterJava). Although that example is adapted for a different stack, the algorithm for the client queue and working with binary data is very familiar to me.

Hello! I will complete everything quickly without questions. I will consult you and deliver the work with quality. To avoid taking 3 days, it will be enough.

Good day! We have experience working with Tamaranga architecture and optimizing media content on the client side. We implement the task using the browser-image-compression library for converting HEIC and compressing images before sending them to the server, which will reduce the load on your VPS. We integrate into the current JS loader by intercepting the change event.
