Photopea vs AI Text Replacement: Six Cases Where Doing It by Hand Still Wins

Photopea is a free, browser-based image editor with Photoshop's toolset, and for some text edits it is still the better choice than any AI replacement tool — including the one this site sells. A disclosure before going further: this is the blog of EditTextImage, an AI tool that replaces text already rendered into a finished image while keeping the typeface and background. That makes us an interested party in this comparison, so the article is written from the other side: six situations where the manual route wins, five where it does not, and the workflow that uses both.

What the two approaches actually do

The manual route removes the old letters by painting over them and then types new ones on a separate layer. In Photopea that means the clone stamp or spot healing tool to cover the text with copies of nearby background, then the text tool with a font you choose, sized and coloured to match. Every decision — what to clone from, which font, how much tracking — is yours, and only the pixels you paint change. Photopea's own walkthrough for this is short and honest: sample with Alt-click, paint over, retype.

The AI route reads the typeface off the pixels, removes the old letters, reconstructs the surface that was behind them from the surrounding image, and renders the replacement in the sampled style. You type the old words and the new words; the model makes every other decision. That is why it is fast on a photograph where nobody has the font, and also why it can be confidently wrong about what was under the text.

Six cases where doing it by hand wins

1. The image cannot leave your machine

Photopea processes the file locally in the browser; an AI tool has to upload it. For a contract mock-up, an unreleased packaging shot, a client's unpublished design or anything with personal data in it, that difference decides the question before quality even comes up. Our own uploads are deleted from storage after roughly seven days under the privacy policy, but they are transmitted and stored in the meantime, and a policy is not the same as never leaving the device.

2. Flat background and a font you already have

When the text sits on a solid colour and the typeface is a system font or one you own, the manual edit is exact and takes a few minutes: fill a rectangle in the background colour, type the new line in the real font, done. There is nothing for a model to reconstruct and nothing for it to sample — it would be guessing at a font you could simply select from a menu.

3. The text crosses a face or the hero product

Reconstruction has to invent whatever the letters were covering, and a guess about a face or the product you are selling is always visible. A person with a clone stamp can source pixels from the other side of the face, follow the curve of a cheek or the edge of a bottle, and decide where a guess is acceptable and where it is not. This is the case we tell people to expect trouble with on our own pages, and it is where manual retouching earns its time.

4. A strong repeating texture

Woven fabric, brick, tile, halftone print: the human eye is unusually good at auditing a repeating rhythm, so a rebuilt patch that is merely statistically similar reads as a patch. Cloning by hand lets you copy whole repeats of the pattern and line them up on the grid, which a reconstruction model does not reliably do. Chalk, paper grain and concrete are different — irregular wear hides seams — but a regular pattern favours the hand.

5. The change is really a layout change

If the new wording is much longer than the old, or needs a different alignment, or a second line, you are not editing text — you are re-setting a block of type. A text replacement tool will make the longer line fit somehow and the result reads as cramped rather than wrong, which is harder to notice and worse to publish. In Photopea you clear the area and set the type properly, with the leading and margins the layout deserves.

6. You need pixel-level control over a master file

For a print master, a brand asset that will be reused for a year, or anything that goes through a reviewer with a loupe, the value of controlling every pixel outweighs the minutes it costs. Layers you can revisit, adjustments you can undo, and a font that is the actual font rather than a rendering of it are the reasons the manual route exists.

Five cases where it does not

The manual route loses whenever the two things it needs — the font and a coverable background — are missing.

• Nobody has the font. Custom, modified or hand-lettered type cannot be selected from a menu, and font identification fails on it more often than people expect. Sampling the letters that are already there is the only way in.
• The background is photographic, gradient or lightly textured. Cloning a believable surface by hand is the skill most manual attempts fail at; a reconstruction model does it well on these surfaces, which is most posters, screenshots and product shots.
• One line, right now. A price, a date, a name. The manual workflow is minutes per line even when it goes well; the AI route is under a minute including the upload.
• No design experience. The clone stamp is easy to learn and hard to do invisibly. If the person doing the edit is a marketer or a shop owner rather than a retoucher, the tool that makes the decisions produces the better result.
• You are on a phone. Photopea works on mobile in the technical sense; cloning with a fingertip does not.

The workflow that uses both

For a difficult image the best answer is usually not either tool but the order in which you use them. Let the AI do the sampling and the unpatterned reconstruction first — that is the part that is tedious by hand — and download the result. Open it in Photopea and inspect at 100%: if one seam broke a pattern, clone across it; if a line was set two pixels off, nudge the layer. The reverse works too: crop and clean the image in Photopea so the model has a simpler surface to rebuild, then run the replacement.

Where that first step is our tool, the honest scope is the same one on the page that rates which backgrounds survive an in-place edit: flat colour and photographic falloff are strong, repeating textures and text over faces are the cases to hand back to a person.

How to do the manual edit in Photopea

1. Open the image (File → Open). Duplicate the layer so the original stays untouched underneath.
2. Select the Clone Stamp (S). Alt-click a clean patch of background next to the text, then paint over the letters. Re-sample often so the grain and light stay continuous; follow any line that passes behind the text.
3. For small marks, switch to the Spot Healing Brush and click them away.
4. Select the Text tool (T), click where the line was, type the new wording, and match font, size, colour and tracking against the untouched text elsewhere in the image.
5. Zoom to 100% and check the seam, the shadow direction and the alignment. Export once — PNG if you can, JPEG at a high quality setting if you must.

Frequently asked questions

Whichever route you take, the same boundary applies: your own posters, screenshots and product images are ordinary work; identity documents, certificates, receipts and official records are not, and neither a clone stamp nor a model changes that. The general comparison of the two tools — price, speed, font handling — is on the Photopea vs EditTextImage page; this article is the part of that comparison that goes the other way.
