A phone photo is 4,000 pixels and 5 MB. Facebook Marketplace, a website and a supplier's form all want something smaller, and half of them reject HEIC on sight.
Three mistakes people make
Stretching a small photo bigger
Enlarging a photo someone sent you by WhatsApp does not add detail, it just adds blur. If the original is small, the listing photo will look soft no matter what tool you use.
Leaving iPhone photos as HEIC
Half the forms and websites out there have never heard of a HEIC file and simply reject it, which is a strange way to lose a customer over a file format.
Uploading the same huge photo everywhere
A 5 MB photo makes a website slow to load and a listing slow to open on mobile data, even though nobody can see the extra pixels once the photo is on screen.
The fix: a whole folder, one instruction
The Jobbit image resizer takes the whole folder, HEIC included, and one job description: convert to JPG, get everything under 200 KB, or make the Instagram size. It resizes, converts and renames the files and hands back one zip, with a note on anything that needed a decision, such as a portrait photo that would lose its subject if forced into a square. The full guide has a size cheat sheet for every platform.
How the free options compare
| What you need | Free image sites | Jobbit |
|---|---|---|
| A whole folder at once | TinyPNG takes 20 images per session | A folder in one message, no counter |
| HEIC accepted | Squoosh and TinyPNG do not take HEIC | HEIC in, JPG, PNG or WebP out |
| The right size for the job | Set a quality slider yourself | Say "under 200 KB" and it aims for that |
A market trader's Sunday photos
A market trader takes fifty product photos on her phone every Sunday for Jobbit to turn into one folder of Marketplace-ready listings, resized, renamed and under a sensible size, instead of resizing them one at a time before she has even packed the van.
When to pay instead
If you design your graphics in Canva every day, its resizer is free with the subscription you already have. For the ordinary job of getting a folder of phone photos usable, a free bulk tool with a size target covers it.
