Sharper Detail From the File You Already Have
Enhancement and enlargement are two different jobs that usually get sold as one. Here is how to tell which one your image actually needs.
Enhance is one of those words that has been used so loosely it now describes almost nothing in particular. Two genuinely different complaints hide inside it. One is that an image is too small: the file does not carry the pixels a print, a hero banner or a marketplace zoom requires, and what you need is a larger canvas. The other is that the image is already the size you want and the detail inside it simply does not read — edges are soft, small texture has collapsed, and lettering in the frame refuses to resolve no matter how it is displayed.
This page is about the second complaint, and saying that plainly is what keeps it from competing with the pages that handle the first. The AI image upscaler covers taking a still up to 4K, and the AI video upscaler does the same job for clips. If the honest answer to your problem is bigger, start there. Stay here if the file has the pixel count you need and what it lacks is clarity. Concretely, that means Fast Enhancer, the image tool in the OpenFilmo workspace, described in its own panel as upscaling and sharpening images, taking PNG or JPG, at 8 credits and an estimated 10 to 25 seconds per run.
What it does
Built for this specific job, not a generic editor.
Sharpening and edge contrast
Local contrast along edges is strengthened, so corners, stitching, eyes and lettering gain definition. This is the same class of loss a lens produces when focus lands a fraction short of where you aimed it.
Apparent texture in flat areas
Fabric weave, foliage, paper grain and fine surfaces read as texture again rather than as blended patches — but only where some structure survived. An area that has been smoothed to nothing has nothing for a sharpening pass to work with.
PNG and JPG in, nothing else
Those two formats are what the tool accepts, at the quality your file already has. Anything else needs exporting first, and PNG avoids adding the extra compression pass that another JPG save introduces.
Continue in the same workspace
An enhanced file stays inside OpenFilmo beside the other live tools. The tools list states that only watermark removal, image enhancement and video HD enhancement are available at present, so those three do not require moving files between accounts.
How it works
Four steps, no timeline to learn.
Start from the best copy you have
Go back to the original export rather than a version that has been shared, screenshotted or re-saved. Every compression pass writes artefacts into the file that are indistinguishable from real detail afterwards.
Export to PNG or JPG
PNG is the safer of the two whenever your editor offers it, because handing over a JPG at the same bit rate it already has costs nothing while re-saving it costs detail.
Run one file and look at 100 percent
Each run costs 8 credits and takes an estimated 10 to 25 seconds. Spend one on the file that worries you most, view the result at actual pixels, and judge before committing the rest.
Decide whether clarity or size was the real problem
If the file still fails because it does not have enough pixels rather than because the pixels are muddy, you have diagnosed a size problem. That is the AI image upscaler, and running enhancement again will spend credits without moving the complaint.
What people use it for
The jobs this actually gets used for.
Photographs that narrowly missed focus
The shot that is almost sharp and not quite, where the subject carries enough residual structure that a sharpening pass makes the difference between usable and discarded.
Files that survived too many exports
Assets that have been resized, re-compressed and re-uploaded until the fine edges went soft, handed over as PNG so no further loss is added on the way.
Scans, receipts and screenshots meant to be read
Documents where the content is a picture already and the failure is legibility — small numerals, hairline borders and type that has gone mushy rather than missing.
Hero images before they go into a layout
A single picture carrying a page or a deck slide, where sharpening at full size is worth more than anything applied later in the design tool.
Why clarity and size are different purchases
Most disappointment with an enhancer is really an unmet expectation about resolution.
A sharpening pass works inside the pixels that exist. It strengthens transitions already present in the data, and a transition has to be there to be strengthened. That is why two photographs which look equally poor in a thumbnail can behave in completely different ways: one carries enough residual detail to build on, and the other lost it somewhere upstream, usually to aggressive downscaling, repeated compression or a lens that never resolved the detail to begin with.
The other half of the distinction is what sharpening does to noise. Contrast is raised everywhere the pass is applied, including in grain and in shadow noise. A file that is both soft and noisy frequently looks worse afterwards, because there is more noise to amplify than there is edge to recover. Sending in the cleanest source available is not pedantry; it is most of the result.
That is also why the split matters before you spend anything. If the diagnosis is genuinely a lack of pixels, enhancement will consume credits without addressing the complaint, and the upscaler is the correct destination. If the pixels are present and merely muddy, enhancement is exactly the right tool, and paying for resolution you cannot perceive is money spent twice on one file.
Credits and plans
Every tool draws on one shared credit balance.
Each enhancement costs 8 credits and takes an estimated 10 to 25 seconds. The Free plan gives 30 credits every month with no credit card, which covers three runs — 24 credits, with six left over — and its exports carry no watermark and include commercial use, alongside 720p export, one task at a time and standard speed. Starter is $9 a month for 400 credits and two parallel tasks; Pro is $19 for 1,000 credits, three tasks and a priority queue; Studio is $59 for 4,000 credits, six tasks and API access.

Frequently asked questions
How much does one enhancement cost?
Eight credits per run, drawn from the same balance as generation and video work. The Free plan gives 30 credits a month with no credit card, which is three runs — 24 credits — before you pay anything. Paid plans start at $9 for 400 credits.
Which file formats does the enhancer accept?
PNG and JPG. Those are the supported inputs, so anything else needs exporting to one of them first. Where your editor offers a choice, PNG is preferable because it does not add another compression pass.
How is this different from your AI image upscaler?
The upscaler page addresses size — taking an image up to 4K. This page addresses clarity inside the pixels you already have. Fast Enhancer is described in its panel as upscaling and sharpening, but no magnification factor is published, so anything that depends on a specific output resolution belongs on the upscaler page.
Will it rescue a badly blurred photograph?
Some files improve noticeably and some barely change. Where the edge retains any residual contrast there is something to strengthen; where an area has been smoothed flat, there is not. It is also not a restoration tool — scratches, faded colour, torn prints and missing detail are outside what a sharpening pass does.
Can I use the enhanced image commercially?
Yes. Commercial use is included on the Free plan as well as on paid plans, and exports carry no watermark. You still need the rights to the underlying picture: enhancing a file does not transfer ownership of it.
