EditTextImage is an online AI tool that edits text in images while keeping the original font, color, size, lighting and perspective perfectly intact. Upload any image — a poster, screenshot, product photo, thumbnail or AI-generated artwork — type the original text and its replacement, and download a 2K-resolution result in about 12 seconds. No Photoshop, no font hunting, no design skills, and no subscription: you buy one-time credit packs that never expire, and failed edits are automatically refunded. Every new account gets 1 free credit — no credit card required.
EditTextImage (edittextimage.com) is an AI-powered image text editor that lets anyone replace, change or fix text inside an image without Photoshop or design skills.
Most image editors fail at this exact job: they reset the font, smear the background, or warp the perspective the moment you touch the text. EditTextImage samples the typography from the visible pixels and re-renders your new text in the same font, weight, color, shadow and perspective — while every pixel around the text stays exactly where it was. There is no font identification step, no manual content-aware fill, and no color matching by eye.
WHAT YOU CAN EDIT
It works on any image with legible text: posters and flyers, screenshots, YouTube / TikTok / Instagram thumbnails, product photos and packaging, menus, banners, memes, and AI-generated images. Two scenarios deserve a special mention:
• Fix garbled text in AI images — Midjourney, DALL-E and Stable Diffusion are famous for producing mangled lettering. Instead of re-rolling the prompt, fix just the text and keep the artwork.
• Translate text in image — swap the language of the text in place (e.g. English → Spanish app screenshots) while the design stays pixel-identical.
SPEED, QUALITY, FORMATS
Uploads accept PNG, JPEG and WebP up to 10 MB. The average edit takes about 12 seconds and downloads at 2K resolution, ready for print, web or social media. A built-in before/after compare lets you verify the result before downloading. An official Chrome extension adds a right-click "Edit text in this image" flow for any image on any webpage.
HONEST PRICING
No subscription. You buy one-time credit packs (from $9.90 for 30 credits) that never expire; one credit equals one text-edit generation. Failed generations are automatically detected and refunded to your balance — you only pay for results. Full commercial rights are included on every image you generate. New accounts get 1 free credit with no credit card required.
PRIVACY AND RESPONSIBLE USE
Uploaded images and generated results are automatically deleted from storage about 7 days after the edit. EditTextImage enforces a strict Acceptable Use Policy: government IDs, official or stamped documents, currency, and deceptive edits are blocked. It is a tool for fixing and localizing your own designs, not for forging documents.
The interface is available in 9 languages: English, Spanish, French, German, Japanese, Korean, Portuguese, Russian and Traditional Chinese.
