1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsScreenshotNeo is the first alternative to try if you want an API that returns a screenshot without managing a browser: its clean-shot processing removes supported consent banners, newsletter popups and chat widgets, and it bills only clean shots. For a specifically documented fractional device-pixel ratio (DPR), however, ScreenshotOne is the clearest match: its options documentation accepts device_scale_factor values from 1 to 5, including 2.25. Browserless also documents device scale factor, but the guide reviewed here does not specify whether fractional values are accepted.
This is a comparison of documented controls, not a hands-on quality, speed or reliability test. The right choice depends on the DPR values you need and whether you want a hosted screenshot API or to operate browser automation yourself.
Which screenshot API is best for custom DPR?
For an explicitly documented custom fractional DPR, ScreenshotOne is the strongest documented fit: it names the device_scale_factor option, gives a supported range of 1–5, and includes 2.25 as an example. Its documentation also describes viewport dimensions separately and says an explicit scale factor can override the value from a device preset. ScreenshotOne’s options documentation establishes those controls; it does not establish comparative image quality or service performance.
For a hosted API that handles clean captures, consider ScreenshotNeo. Its published product facts describe 63 capture options, including 12 device presets and any viewport, but do not specify a custom fractional DPR range. If an exact fractional factor is a hard requirement, verify support with ScreenshotNeo before building around it; do not assume that a viewport or preset implies arbitrary DPR values.

- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Compare the documented controls
| Option | What the cited official documentation establishes | What to verify |
|---|---|---|
| ScreenshotNeo | Hosted screenshot API and MCP server; supports device presets and custom viewport sizes. Clean-shot processing removes supported consent banners, newsletter popups and chat widgets; response headers indicate page verdict and billing. The supplied product information does not specify a numeric DPR range. | Ask whether your required fractional DPR is accepted and how it interacts with presets before relying on it. |
| ScreenshotOne | device_scale_factor range 1–5, including fractional 2.25; explicit viewport width and height; explicit settings can override preset settings. Options documentation and viewport device documentation. |
Check current pricing, plan limits, throughput and service terms directly with the vendor; those were not established here. |
| Browserless | Screenshot REST API guide lists viewport sizing, device scale factor, full-page capture, clipping, output formats and element selectors. Screenshot REST API guide. | Confirm the exact accepted scale-factor values, especially fractional values, in the current full API reference. |
| Playwright, self-managed | Screenshot output can use CSS-pixel or device-pixel scale; device scale creates one output pixel per device pixel and can make high-DPI screenshots larger. Page screenshot API. | Budget for operating the browser runtime and its infrastructure. The documented scale choice is CSS or device, not a numeric custom DPR parameter. |
Set viewport and DPR as separate controls
A viewport defines the browser’s CSS layout area; DPR determines how many image pixels represent each CSS pixel. If a page is captured at a CSS viewport of 800 by 600 with a device scale factor of 2, the raster output can be 1600 by 1200 pixels before any separate resizing or cropping. This arithmetic describes the relationship, not a guarantee about every API’s post-processing.
Keep image resizing distinct from DPR. Resizing an already captured image changes its output dimensions; it does not cause the browser to render the page at a different device scale factor. Likewise, a device preset is a bundle of settings, not proof that its DPR is the one your task requires.

ScreenshotOne setup
- Choose the CSS viewport width and height for the layout you want to test.
- Set
device_scale_factorto the required number, such as2.25, within the documented 1–5 range. - If starting from a device preset, pass the explicit viewport and factor you need. ScreenshotOne documents those explicit values as able to override corresponding preset settings.
- Check the resulting image’s pixel dimensions and inspect the page layout. Account for any later crop or resize separately.
Browserless setup
The REST guide documents both viewport sizing and device scale factor, but the reviewed guide does not confirm fractional values or a numeric range. Use the official Browserless screenshot guide for the request shape and verify fractional support against its full current API reference before sending a production request that depends on it. This avoids presenting an unverified number as a copy-paste-ready setting.
Playwright setup
With Playwright, select screenshot scale as css or device according to whether you want one output pixel per CSS pixel or device-pixel output. That choice is useful for high-DPI rendering but does not provide the same documented numeric control as ScreenshotOne’s device_scale_factor.

What to evaluate before choosing
- Exact factor: If fractional DPR is essential, require documentation or vendor confirmation for the particular value you will send.
- Viewport independence: Confirm you can set the CSS width and height independently of device scale factor, especially when reproducing a responsive breakpoint.
- Preset precedence: Determine which explicit values override a device preset and which preset behaviors remain active.
- Output workflow: Compare required formats, full-page or element capture, clipping, and whether the result should be returned synchronously or handled through a job workflow.
- Operations: A hosted API avoids operating the browser runtime yourself; self-managed Playwright offers browser automation but entails maintaining that runtime and related infrastructure.
- Commercial terms: Confirm current quotas, pricing, throughput and service-level terms directly. They are not established by the cited DPR documentation.

Does the reviewed Browserless screenshot guide confirm fractional DPR support?
It documents a device scale factor option, but the guide reviewed here does not publish accepted values or confirm fractional support.
Is Playwright’s device-scale screenshot setting an arbitrary numeric DPR control?
No. The cited Page API documents a choice between CSS-scale and device-scale output, not an arbitrary numeric DPR parameter.
