Try a photo tool before you pay

Paying first and hoping the result is usable

Anyone who has bought credits for an online photo tool knows the feeling. You upload a product shot, the site asks for payment before it does anything, and only after the money has gone do you find out that the edges around the hair are ragged or that the cut-out has eaten part of the handle. At that point the credit is spent and the only option left is to try again and pay again.

The other common pattern is not much better. The site does process your image, but what it shows you is a small thumbnail, often covered in a watermark, at a size where every result looks fine. A thumbnail hides exactly the defects that matter: a grey fringe around a curl of hair, a smeared texture on skin, a halo along a sharpened edge. You only see them once you have paid for the full file and opened it on a proper screen.

So the fear is reasonable. You are not really paying for processing, you are paying for a result you have not been allowed to inspect. The fair way round is the opposite: let people try the photo tool before they pay, show them the real output at a size where they can judge it, and charge only when they decide the file is worth keeping. That is how Airpic is built, and the rest of this article explains how it works in practice and what to check before you spend anything.

See the result before buying credits: how the preview works

On Airpic there is no step where you pay to process. Every job runs in full, on a GPU in the European Union, without an account and without a card. When it finishes you get the actual result of the model on your own picture, not a mock-up and not a sample from someone else's photo.

What you can do with that result before paying:

• Before and after comparison. The result opens in a comparator with a slider: drag it across the image and you see your original on one side and the processed version on the other, in the same position. It is the quickest way to spot anything the tool has changed that it should not have.
• View at 100 %. A button switches the preview to real pixel size, with scrolling, so you can move around the picture and look at edges, hair and fine texture one pixel at a time instead of judging a scaled-down version.
• Several candidates in reference restoration. When you restore an old photo and add reference pictures of the same person, the tool produces several candidates, each with a likeness score, and lets you click between them. You choose the one that looks like the person you remember, and the comparator and the download follow your choice.

The only thing that costs anything is the full download. Each month you get one free full download; after that, a download uses a credit. Credits are bearer codes kept in your browser, there is no subscription behind them and they never expire. The prices for each tool are on the tool page itself, so you can check them at the moment you decide rather than relying on a figure in an article.

One tool is an exception: if you need to compress images, processing and downloading are both free, with no credits involved at all. It runs on CPU in a few seconds, so there is nothing to protect with a preview.

Refund if the result is bad: what happens when a job fails

Two different situations get mixed up under the word refund, so it helps to separate them.

The job fails. Sometimes a file cannot be processed: a corrupt image, a format the browser sent badly, a worker that crashed. In that case you are not charged. With the image tools nothing is taken before the download, so a failed job simply never reaches the point where a credit is used. Where a tool does reserve credits before it starts, the credits are returned automatically if the job fails. You do not need to write in or open a ticket.

The job works but the result is not good enough. This is the more common case, and the answer is simpler still: you do not download, so you do not pay. The preview exists so that the decision happens before any money moves. If the cut-out around a bicycle wheel is not clean, or the upscale has made a face look waxy, close the result, adjust the settings and run it again. Every attempt is processed for free; only the file you finally keep costs a download.

There is no money-back guarantee in the usual sense because there is nothing to give back: the system is designed so that you never pay for a result you have not seen. What there is, under every tool, is a link that reads roughly "Result not good? Tell us". It opens an email with the name of the tool and the job reference already filled in. Those messages are read, and they are how the tools get better on the kinds of photos people actually bring.

A practical point: results do not wait forever. Files are deleted at most one hour after you download them, or one day after processing if you never download. If you want to think about a result, think the same day.

What to check in the preview before you pay

A preview only protects you if you look at the right places. Each tool has its own typical failure, and each one is visible in the 100 % view if you know where to go.

Background removal: the hair and the thin parts. Zoom to 100 % on the outline of the hair, especially loose strands against a light or busy background. Look for a grey or coloured fringe left over from the old background, strands that have been cut off in a straight line, or gaps where fine hair should be. Then check the thin parts of the object: straps, chair legs, the space between fingers, the inside of a handle. If you plan to place the cut-out on white, switch the background to white in the options and check again, because a fringe that is invisible on a checkerboard can show clearly on white.

Upscaling: skin, text and repeated texture. When you upscale an image, the first thing to inspect is skin. It should keep its pores and small irregularities, not turn into a smooth, plastic surface. Then look at any text, logos or numbers: letters should stay the same shape, not be redrawn. Finally check fabric, grass, brick or hair, where an upscaler can produce a pattern that repeats too regularly. If you are preparing a print, the guide to upscaling for large-format printing explains which factor you actually need for the viewing distance.

Sharpening: halos and invented edges. With a tool to unblur a photo, look along strong edges, such as a dark roofline against the sky or the outline of a face. A thin bright or dark line running parallel to the edge is a halo, and it means the strength is too high. Lower the intensity slider and run it again; the slider is there precisely so that you can find the point where the photo is sharper without looking processed.

Noise reduction and restoration: where detail ends. After you remove noise from a photo, check areas that should have texture, like hair or foliage, to make sure they have not been flattened into a smear. With restoration, compare the face side by side with the original: the expression, the shape of the mouth and the eyes should be those of the person, not a generic face. If they drift, lower the fidelity slider or add a reference photo.

A good habit for any tool: drag the comparator slider slowly across the most important area of the picture, then switch to 100 % and pan over the same area. Most problems show up in one of those two views within a minute.

Free background removal preview, step by step

Here is the whole process with the tool to remove the background from a photo, from upload to the decision to pay or not.

1. Upload the photo. Drag it onto the page, pick it from your files or paste it with Ctrl+V. JPG, PNG (including transparency and 16-bit), WebP, TIFF, HEIC and AVIF are accepted. The EXIF orientation is applied and the ICC colour profile is kept, so a photo straight from a phone arrives the right way up and with its colours intact.
2. Choose the background. Transparent if you will place the cut-out on a design, white for marketplaces such as Amazon, eBay or Etsy, black, or any colour as a hex code. The edges are calculated at full resolution, hair included, so the choice of background does not change the quality of the cut.
3. Process. Press the button and wait for the result. Nothing is charged at this step, however many times you repeat it.
4. Compare. Drag the before and after slider across the subject, paying attention to the outline.
5. View at 100 %. Open the real-size view and pan over the hair, the thin parts and the bottom edge, where the object meets the old floor or table. This is where a fringe or a missing piece would show.
6. Decide. If something is wrong, change the background colour or the output format and process again. If a small area needs a touch-up, the retouch brushes on the result let you bring back or erase parts of the mask before downloading, and the full file is rebuilt with your strokes.
7. Download only if it convinces you. The full download uses your free download of the month or a credit. If it does not convince you, close the page: you have paid nothing and the files are deleted automatically.

For product photos in particular, the article on white background product photos covers lighting and framing so that the cut-out starts from a good original, and the guide to removing the background from an image goes deeper into tricky subjects like glass and fur. When you are ready, upload your photo to the background remover, check the result at 100 % and decide afterwards.
