Web hosting for interior designers — There is a compression level your photography survives, and you can find it
Designers under-compress because a flattened colour looks amateurish, and over-compressed sites are only half the problem — the other half is finding the actual threshold.
The short answer
Test your way to the compression level your work survives instead of guessing at it. Take one representative photograph — a room with a strong paint colour and a textile — export it at several quality settings, and look at them side by side on a calibrated screen and then on a phone. There is almost always a setting well below your instinct where the difference is invisible and the file is a fraction of the size.
That is the single highest-value hour available on a design portfolio. The platform handles the rest: automatic WebP conversion, responsive sizes, NVMe storage on every tier and LiteSpeed caching inside the web server, with free SSL, free migration and support at any hour.

Interior design sites carry a real tension that most image-heavy sites do not. Colour and texture are the product, so aggressive compression is not a neutral trade — a flattened green or a smeared boucle genuinely misrepresents the work. The usual response is to compress barely at all, which produces pages that fail on a phone.
Both positions are avoidable, because the relationship between quality setting and visible difference is not linear. Files fall off a cliff in size long before they fall off a cliff in appearance, and the only way to find that point is to look at your own photography rather than to follow a general recommendation.
The second thing worth measuring on these sites is the filter. Tagging projects by room and style is right for visitors, and a filter that rebuilds the whole grid on every click is an interaction cost that shows up in your field data.
Find the threshold with your own photography
Pick the hardest image you have: a room with a saturated wall colour, a natural fabric and some fine pattern. Export it at a spread of quality settings, then compare them at the size they will actually render at — not zoomed in. Note the file size of each. The point where you can first see a difference is your ceiling, and it is usually a good deal lower than instinct suggests.
Then check the same set on a phone screen in ordinary light, because that is where the work will be judged. Automatic WebP conversion applies on top of whatever you upload, so your export setting establishes the quality floor for everything the platform derives from it.
Dimensions matter more than quality settings
Before spending an afternoon on compression, check dimensions. A photograph uploaded at 4000 pixels wide and displayed in a 900-pixel column is paying for four times the pixels regardless of how it was compressed, and no quality setting recovers that. Compare intrinsic size against displayed size in the DevTools network panel for the images on your busiest project page.
The platform generates responsive sizes, so a phone can be served a smaller file if your markup lets it. Upload at roughly twice the widest display width, keep one image above the fold eager, and lazy-load the rest. Those three rules do more for a gallery than any compression decision.
The filter is an interaction, and it is measured
Filtering by room type or style is the right structure for a design portfolio, but the implementation decides what it costs. A filter that re-renders the entire grid, or fetches a fresh page of results on each click, produces a long task on the main thread — and Interaction to Next Paint takes close to the worst interaction on the page, with a good threshold of 200 milliseconds at the 75th percentile.
Measure it properly: open the performance panel, record while you click through three filters, and look for long tasks. Showing and hiding items already in the DOM is dramatically cheaper than rebuilding the grid, and on a portfolio of thirty projects it is entirely sufficient.
Test on the device, not the desk
Design studios have good hardware and good screens, which is exactly the wrong equipment for this measurement. Use a mid-range handset on mobile data, or at minimum a DevTools run with both network and CPU throttling enabled, because decoding large photographs is real work on a phone and the CPU setting often changes the result more than the network one.
Then let the field report confirm it. It reads a rolling 28-day window of real visits and grades LCP at or under 2.5 seconds, INP at or under 200 ms and CLS at or under 0.1 at the 75th percentile. That is the verdict; a lab number is a hypothesis about it.
What the platform does with what you upload
Automatic WebP conversion and responsive sizes are generated from your original, so the format and variant work is done without a plugin or a settings page.
NVMe storage and LiteSpeed caching in the web server carry the pages themselves. Staging copies let you re-process a library and compare before anything reaches a client mid-enquiry.
- WebP conversion applied to what you upload
- Responsive sizes derived for narrower screens
- NVMe storage throughout, cheapest tier included
- LiteSpeed cache part of the stack, not bolted on later
Why HostingFast
Standard on every plan
A quality floor you chose
Your export setting establishes the quality everything else derives from, so the decision is made once by someone who can see the difference.
Format and variants handled
Automatic WebP conversion and responsive sizes mean the platform does the mechanical work and leaves you the judgement calls.
Somewhere to re-process safely
Staging copies let you rebuild an image library and compare the numbers before the live site ever shows a client the result.
Rollback for a bulk media job
Daily backups recover files, a database or both from the panel — the reason a bulk media job is a reasonable thing to attempt at all.
No certificate warning on arrival
Free SSL on every plan, reissued before expiry, so a browser warning never greets somebody arriving from a magazine link.
Support that will open the gallery
Humans who will look at a slow gallery with you rather than replying that the server is fine and closing the ticket.
Quick Start
From order to online
- 1
Establish your compression ceiling
One hard image, several quality settings, compared at display size on a good screen and then on a phone. An hour, once, and it applies to everything afterwards.
- 2
Fix dimensions before quality
Intrinsic versus displayed width in the network panel. An oversized image is wasted bytes no compression setting can recover.
- 3
Record a trace while filtering
Performance panel, three filter clicks, look for long tasks. Showing and hiding beats rebuilding the grid on a portfolio of this size.

- Uploads at roughly twice the widest display width, not camera resolution
- One eager image above the fold; everything else lazy-loaded
- Filter interaction traced in the performance panel for long tasks

- Field vitals read at the 75th percentile before declaring the work done
Frequently Asked
What people ask us most often
How do I compress photography without ruining the colour?
By finding the threshold on your own images rather than accepting a general figure. Export your hardest photograph at several quality settings, compare them at the size they will actually render and then on a phone, and note where a visible difference first appears. File size falls away much faster than perceived quality does, so the usable setting is normally well below what instinct suggests.
Should I worry about compression or about dimensions first?
Dimensions, every time. A 4000-pixel photograph in a 900-pixel column wastes three quarters of its pixels no matter how carefully it was compressed, and that waste is invisible in any quality comparison. Check intrinsic against displayed width in the network panel first; the compression conversation is worth having afterwards and is usually smaller than expected.
Is a filtered project grid bad for performance?
Only if it is implemented expensively. Filtering by room and style is the right structure for visitors. What costs you is rebuilding the whole grid or fetching new results on every click, which creates long tasks on the main thread and shows up in your INP figure. On a portfolio of a few dozen projects, showing and hiding items already present is both simpler and faster.
Why does the gallery feel fine on my monitor and slow on a phone?
Two reasons compounding. The network is slower, and the CPU has to decode large photographs with far less power available. That second half surprises people, and it is why the CPU throttling setting in DevTools often changes a result more than the network profile does. Test on a mid-range handset if you can, and with both throttles engaged if you cannot.
