the challenge
ONE HEAVY IMAGE. SLOWER MOBILE PAGES.
The subscription form carried a 1.05 MB image, and it was slowing mobile page loading. The image needed real transparency to sit cleanly over the design, so a quick switch to a flat format was off the table.
our solution
LESS WEIGHT, SAME TRANSPARENCY, LIGHTER MOBILE PAGE.
We resized the signup image to the dimensions the form actually uses and compressed it losslessly as PNG, so the transparency stays crisp.

timeline
HOW THE LIGHTER PAGE SHIPPED.
- Foundation
As the team developing and supporting the store since 2023, we know where its weight sits and spotted the oversized signup image.
- Build & ship
The image was resized, compressed as PNG and swapped into the live form with its transparency intact.
- Compound
Every mobile visit now carries the lighter file, and the same approach is ready for the rest of the store's visuals.
asked about this case
Why does a single image matter for an online store?
The signup form appears to mobile shoppers across the store, so its weight is paid on many visits. Cutting it from 1.05 MB to 460 KB lightens every one of them.
Did the form lose quality or transparency?
No. We kept PNG and compressed it losslessly, so the transparent edges sit over the design exactly as before.
Was this a one-off fix?
It is part of ongoing development and support for the store since 2023. We tracked the file weight; load time and sales impact were not measured separately.
Can you do the same for my store?
Yes. We start by finding the heaviest files on your mobile pages, then resize and compress them without changing how your brand looks.
