Printcart's measured 2x upscale results on four print-test images next to Let's Enhance's published plans, limits and prices, read on 2026-10-06. This guide shows the practical setup decisions, Printcart tools, and production checks needed to apply it.
Key takeaways
Updated on 2026-10-07. Printcart publishes this comparison and makes one of the tools tested. We ran every tool ourselves with the same files and default settings, and we show the cases where other tools did better.
We did not run Let's Enhance. Its terms (clause 3e, effective 2024-03-01) forbid using the service for benchmarking or competitive analysis, and its free tier needs an account. This article therefore shows Printcart's own measured results next to Let's Enhance's published features and prices, each with its source and date. Nothing here compares image quality between the two.
Quick answer. In our 2026-10-06 test, Printcart Image Upscale made 2x PNG files from 4 identical inputs, such as 1920x762 to 3840x1524. We did not run Let's Enhance because its terms forbid benchmarking, so this compares documented features. Choose Let's Enhance for very large outputs; choose Printcart for upscaling inside a Printcart store workflow.

Pixels and file sizes are measured on the Printcart side only. Let's Enhance figures are quotes from its public pricing page.
How we tested
Date, tools and versions
- Printcart Image Upscale (/tools/image-upscale), run 2026-10-06 (UTC) through the service API as the Printcart test account (paid tier, token wallet). Default engine, scale 2x.
- Let's Enhance: not run. Pricing page letsenhance.io/pricing read 2026-10-06; terms letsenhance.io/terms read 2026-10-06.
Input set
| Code | File | Pixels / size | Source and licence | Why it is hard |
|---|---|---|---|---|
| D5 | D5_a4_800.jpg | 800x600 | Phil, used with permission | Soft phone detail |
| D6 | D6_a1_lossy_1200.jpg | 1200x800, 44 KB | Phil, used with permission (JPEG quality 15) | Heavy JPEG compression blocks |
| P4 | P4_logo_300px.png | 300x300 | Printcart test library, fictional brand | Thin serif text at 300 px |
| A16 | A16.jpg | 1920x762, 674 KB | Stock panorama with licence in the library manifest | Water and foliage texture |
Every tool received exactly the same files. Download the inputs and the original outputs (ZIP); each side has a meta.json with the date, URL, plan, settings and file hashes.
Default settings
Printcart: default engine, 2x. Let's Enhance: not run.
Rubric
| Criterion | Weight | How measured | Printcart | Let's Enhance |
|---|---|---|---|---|
| Detail and sharpness | 25 | Crops at 100% | Observed, not scored | Not tested |
| Artefacts | 15 | JPEG blocks, halos at 100% | Observed, not scored | Not tested |
| DPI at print size | 20 | Output pixels divided by inches | Calculated below | Not tested |
| Maximum factor on tested plan | 10 | Highest factor offered | 2x and 4x (page) | Not tested |
| Sign-up and watermark | 10 | First result without an account; watermark | Account needed; none seen | Account needed; watermark on free (pricing page) |
| Batch and API | 10 | Public API; batch | API tested; batch not | API listed; personal-plan batch not stated |
| Price per result | 10 | Plan price divided by results | Priced in tokens (see Pricing) | $9, $24, $34 per month for 100, 300, 500 credits |
No totals: the competitor was not run, so no weighted score is given for either side. Visual scores are provisional: one reviewer (an AI agent working from the saved files) scored them, not the two human graders our standard asks for. The numbers (pixels, bytes, seconds, sharpness metric, decode counts) are measured.
Repeating the test
Results can change as tools update. You can repeat this test: download the same input set, use default settings, and compare at 100% zoom. We re-test every quarter and log changes below.
Results by criterion
Printcart results at 100%
Inputs: stock panorama and Phil's photo (used with permission). Output: Printcart Image Upscale 2x, default settings, 2026-10-06. Left pair A16, right pair D6.
A16 gained clean, smooth texture. On D6 the 2x result is smoother but the blocky JPEG pattern is still visible, so upscaling did not remove compression damage.
Size and DPI at print size
| Input | Printcart output | DPI at 11x14 in (long side 14 in) | DPI at 24x36 in (long side 36 in) |
|---|---|---|---|
| D5 | 1600x1200 PNG, 3.74 MB | 114 | 44 |
| D6 | 2400x1600 PNG, 3.38 MB | 171 | 67 |
| P4 | 600x600 PNG, 72 KB | n/a (square logo) | n/a |
| A16 | 3840x1524 PNG, 12.9 MB | 274 | 107 |
Time per job: 6 to 11 seconds (one run each). Printcart refused our 15.1 MB file A12 with HTTP 422 (limit 10 MB) and spent no tokens.
Let's Enhance, from its public pages
Free plan: 10 credits at sign-up, upscale up to 8 megapixels, watermark. Starter $9/month with 100 credits (up to 256 MP), Pro $24/month with 300 credits (up to 350 MP), Max $34/month with 500 credits (up to 512 MP). Enhancer and Upscaler APIs are listed (letsenhance.io/pricing, read 2026-10-06). Billing is by credit.
Where Let's Enhance wins
- Output ceiling: Let's Enhance documents outputs up to 256, 350 or 512 megapixels on paid plans, far above the 5.9 MP outputs we produced from Printcart's 10 MB upload limit.
- A plainly stated free trial: 10 credits on sign-up, and a published price list per monthly plan.
Where Printcart wins
- No watermark on the Printcart outputs we saw, while Let's Enhance lists a watermark on its free plan.
- Printcart results stay inside the Printcart account and can feed the preflight and store tools (we did not test this chain here).
Pricing and limits (as of 2026-10-06)
- Printcart (api.printcart.com/v1/public/pricing, read 2026-10-07): plans Free 50 tokens a month, Starter $29 for 3,000, Pro $99 for 20,000, Business $299 for 100,000 and Partner $999 for 500,000 (6-month commitment); at Starter, one token is about $0.0097.

Prices change; check the vendor's page.
Who should pick which
- Poster seller who needs very large outputs: Let's Enhance documents far higher output ceilings; verify with its free credits yourself.
- POD store already on Printcart: run the upscale in the Dashboard and check the DPI at your print size.
- Print shop with customer files: upscale only after checking whether a better original exists; compression blocks remain visible.
- Developer: both list an API; we tested only Printcart's.

FAQ
Is Let's Enhance free?
It gives 10 free credits at sign-up with a watermark and up to 8 megapixels per image; paid plans start at $9 per month (letsenhance.io/pricing, 2026-10-06).
Why did you not test Let's Enhance?
Its terms forbid using the service for benchmarking or competitive analysis, so we compared published features and prices only.
Does upscaling fix JPEG compression blocks?
Not in our test: the 2x Printcart result of a heavily compressed JPEG was smoother but still showed the block pattern.
How many pixels do I need for a poster?
Divide pixels by inches. A 24x36 inch print at 150 DPI needs 3600x5400 pixels; at 300 DPI, 7200x10800.
