Hey Indie Hackers,
When I started working with images for social media and eCommerce as I am a graphic designer (contributor at Adobe Stock) , I ran into the same problem over and over: dimension fatigue.
Every platform has its own ideal sizes — Instagram, Facebook, Pinterest, Shopify, Amazon — and remembering them all is exhausting. One wrong size and your images look off, your ads perform poorly, or products don’t display correctly.
That’s why I (devbyisty- a code lover) built ProBatchResizer with 130+ ready-made presets. Instead of looking up sizes every time, you just pick the platform and type of content, and the tool automatically resizes your images instantly and in bulk upto 100s images.

Here’s why it matters:
Save time: No more manual resizing or guesswork.
Consistency: All your images have perfect dimensions, keeping your brand looking professional.
Better performance: Optimized images load faster, perform better in ads, and improve eCommerce listings.
Privacy-first: All processing happens locally in your browser using WebAssembly — no uploads, no servers, no risks.

For anyone running a shop, creating content, or posting regularly, having these presets turns a tedious task into a one-click workflow.
I’d love to hear what features you think would make a bulk image tool even better — especially for social and eCommerce creators.

Congrats on the launch, looks solid. How are you currently thinking about acquiring early users and gathering feedback?
Batch resizing can be a real pain, especially when you have a ton of images to process at once. I once spent way too much time manually resizing product images for a side project, and it totally messed up my workflow. I ended up writing a quick Python script to handle batches, but it wasn’t very user-friendly. What I learned is that automating these repetitive tasks saves a ton of mental bandwidth.
Here are some tips:
* Try to clearly identify the most common resize dimensions you use to avoid overcomplication.
* Make sure your tool can handle different image formats without breaking.
* Consider integrating with your existing workflow or cloud storage to save manual uploads.
* Watch out for image quality loss when resizing, especially if scaling down a lot.
* A simple UI beats flashy features if you want people to actually use it.
Curiosity, did you test this with really large batches? How does it hold up performance-wise?
