Image Resizer Apps vs One AI Agent in 2026: Subscriptions You Can Cancel and the Shop It Builds for You (Canva, TinyPNG, Jobbit)
Image resizer apps vs one AI agent in 2026: Canva Pro is £13 a month, TinyPNG $39 a year and iLoveIMG about $4 a month for resizing photos a free tool does in seconds. What the subscriptions really cost, how to resize HEIC to JPG under 200 KB free, and how the same agent builds the shop, the listings and the catalogue your photos belong in.
Your phone takes a 4 MB HEIC photo. Etsy wants a JPG, the council website wants it under 2 MB, the parish newsletter wants 800 pixels wide and Instagram wants a square. So you pay Canva £13 a month, or TinyPNG $39 a year, or an app in the App Store £4.99 a week, for arithmetic a computer did for free in 1998. Nine in ten UK adults now hold a subscription and the average household has lost track of £576 a year of them. Image resizer apps are among the easiest to forget, because the job is small and the charge is quiet.
This guide is for the person who takes photos of things they make, sell, rent or teach. It shows what the subscriptions really buy, how to resize, convert and compress any image free in seconds, and then the thing the app companies would rather you did not notice: the AI agent that resizes your photos can build the shop, write the listings, lay out the catalogue and host the whole thing on your own domain. If the photos are of something you made, you are closer to a business than you think.
Need a photo the right size now? The free image resizer converts HEIC to JPG, WebP or PNG, resizes to exact pixels or a platform preset, and hits a size in KB, on the Free plan's 100 credits a day, no card.
What you are really paying for
| Service | Plan | Price | What you actually use | Per year | The catch |
|---|---|---|---|---|---|
| Canva | Pro | £13 a month or £100 a year plus VAT | Magic Resize, background remover | £156 | Free plan resizes one design at a time |
| TinyPNG | Web Pro | $39 a year, Ultra $149 | Batch compression over 20 images | about £31 to £118 | No HEIC input, no size target |
| iLoveIMG | Premium | about $4 a month | No caps, no queue at peak | about £38 | Free tier has task and size caps |
| Compressor.io | Pro | $50 a year | Unlimited compressions | about £40 | Free is 50 a day, 10 MB each |
| Squoosh | Free | £0 | Everything, one image at a time, in the browser | £0 | No batch |
| Jobbit image resizer | Free plan | £0, 100 credits a day | HEIC in, JPG, PNG, WebP out, size in KB, exact pixels or presets, a whole folder per message | £0 | Hosting a shop is paid; the tool is not |
The picture is the same as every single-purpose app: the free tiers are fenced to make you feel the limit, the paid tiers charge £30 to £156 a year for the fence to go away, and the underlying job costs nothing. The image compressors head to head tests them on the same files; the resize and convert images free guide covers 14 sizes for every platform.
When a paid image tool is worth it
Canva Pro is a fair price for a designer who makes forty social posts a week from templates and needs brand kits and a team. TinyPNG's API is fair for a developer compressing thousands of product images automatically. If you take photos of your knitting, your cakes, your holiday cottage or your restored furniture and need them the right size for a listing, you are not that customer, and every one of those tools has a free path they hope you will not find.
The free way, in seconds
- Open the image resizer and drop the photos, HEIC straight from an iPhone is fine.
- Choose the output: JPG for listings and email, WebP for a website, PNG when you need transparency.
- Set the size two ways: exact pixels (Etsy listing 2000 by 2000, Instagram 1080 square, a website hero 1600 wide) or a target in KB ("under 200 KB") so the page loads fast.
- Download one or the whole batch. A folder of 60 photos is one message to the agent: "make me a 2000 square JPG and a 400 pixel thumbnail of each".
- Keep the originals. The resized copies are for the web; the originals are for print.
The same agent, the bigger job
General assistants such as ChatGPT, Claude, Gemini, Copilot, Manus and Meta's Muse will write a nice product description if you paste one in. Jobbit's agent takes the folder of photos and builds the business around them:
- The listings. Titles, descriptions, materials, care instructions and keywords for each product, written from the photo and two lines from you, in the tone you choose.
- The catalogue. A printable PDF and a web catalogue with prices, laid out from the same photos, updated when you say "the blue one is sold".
- Your own shop. A site with product pages, a basket, your Stripe or PayPal checkout and a contact form, hosted with your own domain from £7 a month on the Go plan, so the marketplace fee is no longer the only route.
- The marketplace feed too. The same products exported in Etsy's or eBay's format, so you sell in both places without typing everything twice.
- Photos that sell. Background removed, colours consistent, a lifestyle mock-up for the hero image, all from the originals.
- The newsletter and the posts. A monthly email to customers and a week of social posts from the new batch of work.
Anne, 70, and the jumpers that went to Etsy
Anne knits. For three years she sold through a marketplace, photographing each jumper on a chair with her phone, paying an app to shrink the pictures, and paying the marketplace's listing and transaction fees on every sale. In January she gave the agent a folder of 80 photos and a list of prices. It resized and cleaned the photos, wrote 80 listings with sizes and yarn details, built her own shop with a checkout and a "commission a jumper" form, and exported the lot to the marketplace as well. Repeat customers now buy on her site, where there is no fee per sale; new customers still find her on the marketplace. She spends the app money on yarn.
Marketplace fees vs a shop of your own
The resizer subscription is the small leak. The marketplace is the big one, and it is worth knowing the numbers before you decide where the photos go. Etsy charges UK sellers a listing fee of £0.15 per item for four months, a 6.5% transaction fee on the item price plus postage, a payment processing fee of 4% plus £0.20 per order, a 0.25% regulatory operating fee, and 20% VAT on all of those fees. Offsite Ads add 12 to 15% on any sale they bring in. The 2026 fee guides put the total at 10 to 13% of a typical sale, and 25 to 30% on items under £10.
Take a £45 jumper with £4 postage. The transaction fee is £3.19, payment processing £2.16, the listing £0.15 and the regulatory fee £0.12, about £5.60 before VAT on the fees and before any advert. Twenty sales a month is about £115 in fees, close to £1,400 a year. A shop of your own on the Go plan costs £70 a year on annual billing plus your payment provider's card fee, typically about 1.5% plus 20p on a UK card, so the same twenty sales cost about £17 a month.
The honest strategy is both. The marketplace brings strangers; keep it for discovery. Your own shop keeps the repeat customers, the commissions and the mailing list, and every sale that moves across saves you the fees. The agent builds the shop and keeps both catalogues in step, so the choice costs you an afternoon, not a developer.
Retired, with time, money and one idea
Anne is part of the biggest group of new business founders in Britain. Over-50s are 42% of the UK's self-employed, self-employment over 65 has more than doubled in five years, and older founders' businesses survive five years at over 70%, against 28% for the young. Wealth peaks between 65 and 74. What holds most of them at the hobby stage is not money or time; it is the belief that a shop needs a web designer, a photographer and a developer.
In 2026 it needs a folder of photos and an afternoon. The agent does the resizing, and then it does everything the resizing was for. If you have made things for years and never sold them properly, the website, app or automation built today guide shows the conversation that gets a shop live.
The truth: what the agent will not do for you
- It cannot fix a bad photo. Light, focus and a plain background still come from you. It can clean up and match colours; it cannot invent detail.
- It will not choose your prices. It can research what similar work sells for; the number is yours.
- A shop needs traffic. Your own site removes the fee, not the need for customers. Keep the marketplace until the site earns its keep.
- Hosting is the paid part. Resizing, listings and previews run on the Free plan; keeping the shop live on your domain is £7 a month.
- Check the copy. Materials, sizes and care instructions are claims; read them before they go live.
- Rights are yours to check. Only upload photos you took or own.
Your first week
- Day 1: cancel the resizer. Do this week's photos with the free tool and note what you paid for last month.
- Day 2: the folder. Put the best 20 photos in one place with a price and two lines each.
- Day 3: listings. Ask the agent for titles, descriptions and keywords, in your voice. Correct five; it learns the rest.
- Day 4: the shop preview. Ask for a shop with those 20 products and your payment link. Look at it on your phone.
- Day 5: the marketplace export. Same products, their format.
- Day 6 to 7: tell people. A newsletter to past customers and a week of posts, resized from the same photos. The first week with an AI agent guide covers the briefing habits that make this stick.
