The short answer

What does the add text to photo do?

Imagera lets you add text to image files in your browser on a phone, tablet or computer. The Add Text to Photo editor draws a caption over a JPG, PNG, WebP or HEIC picture for social posts, invitations or product announcements. Choose a style and position; the words wrap and shrink to fit. The photo is processed on your device. 2 free downloads, 8 more after sign-in.

Good to know

Did you know? Photo captions facts

  1. The caption field has a 120-character limit. Some emoji use more than one character of that allowance, so keep symbol-heavy captions short.

  2. On a 1000-pixel-wide working image, the caption fitter measures against an 880-pixel width, including space for the selected text effect.

  3. Each run draws 1 new caption block. Existing lettering remains part of the picture; Photo Text Changer handles changes to those words.

    Try Photo Text Changer

Give a photo caption contrast against the scene

Put an event date, a short quote or an offer over a photo you already have. The available looks are Clean with shadow, Bold outline, Caption box, Neon glow or Elegant serif; the starting style is Clean with shadow. Each look supplies its own lettering and effect rather than opening a full design editor.

An outline can separate letters from a busy scene. A caption box puts a solid shape behind each line, while a shadow leaves more of the photograph visible. Check the caption over both light and dark parts of your picture. Choose the effect for readability, then check that it suits the photo.

Why a longer caption changes the lettering size

The tool measures your words, tries smaller lettering when needed and balances the wrapped lines. In Advanced, Text size sets the largest requested size as a percentage of the picture’s shorter side. It is a ceiling, not a fixed size that every caption will reach.

Typed line breaks and repeated spaces become ordinary spaces before fitting. Capitalization stays as you typed it. If the result feels crowded, shorten the wording and run it again. The fitter aims for a limited block of lines, but unusually narrow or tiny pictures can still need a shorter caption.

Place the caption without covering the subject

Use Position to choose Top, Center or Bottom; it starts at Bottom. Lines are centered horizontally, with space reserved near the image edges. Choose the area with fewer details and check whether the words cover a face or an important part of a product.

There is no drag handle, rotation setting or independent second text box. The caption sits over the photo: it cannot wrap around a person, pass behind a building or extend the canvas with a description underneath. A layered layout editor is needed for those arrangements.

The saved caption becomes part of the picture

The result combines the photo and lettering into one image. You can change the wording and run it again while working from the original, but reopening the saved result does not restore an editable text layer. Keep an uncaptioned source for later revisions.

The caption is drawn on the decoded image canvas, not on a screenshot of the preview. Very large pictures can be reduced to the browser’s canvas limits, and the result shows its resolution. The saved file type follows the engine’s output rules and may differ from the source; adding text is not a promise of unchanged compression or file size.

Draw personal captions on the device holding the photo

The image is read locally and the browser draws your caption onto it. There is no photo upload in this processing path. A phone can handle the same caption controls as a computer, although available memory limits very large images.

The website still needs its code and fonts, and it can make service requests or report processing errors. If caption rendering fails on a large picture, keep the original and retry the lettering on a reduced copy.

Choose between a new caption and changing a photographed sign

This editor paints the words you supply over the existing picture. It does not recognize letters on a sign, erase their old shapes or recreate the surface behind them. Drawing a new caption across an old label can leave both visible.

For an incorrect word already printed in a picture, use the linked Photo Text Changer. That is a separate editing job. Finish changes to the scene or its existing lettering first, then return here if the final photo also needs a caption.

How do you use the add text to photo?

  1. Pick the photo to caption

    Choose a JPG, PNG, WebP or HEIC picture with room for the words you want to add.

  2. Write and style the caption

    Enter your wording, then choose Style and Position. Open Advanced to adjust Color or Text size.

  3. Draw the text and inspect it

    Press Add text and check spelling, contrast and subject overlap. Review the result resolution before using it in your design.

  4. Save your result

Add Text to Photo: questions and answers

How do I put words on a picture online?

Open the picture, enter a caption and select its look and placement. Run Add text to create the captioned image. Review the wording before saving the result.

Can I choose a custom font for my caption?

There is no font picker or font upload. The style selects a sans-serif font stack led by Inter or a serif stack led by Georgia, with fallbacks if a font is unavailable.

How much writing fits in the text field?

The field accepts up to 120 characters, and the engine also clips text at that limit. Emoji can consume multiple units. Use a short caption rather than a paragraph for a clearer result.

Can I overlay multiple lines and keep my own line breaks?

Longer wording wraps automatically. Manual line breaks are converted to spaces, so the tool decides where the displayed lines end. It keeps your letter case while balancing the line lengths.

Why does a long caption become small or run near the edge?

Fitting can reduce the requested size to accommodate the words. Shorten the caption first; a very narrow source can still be awkward at the smallest fitting size. Increasing Text size will not force a long sentence to remain large.

Can I drag or rotate the words to an exact spot?

No. Placement uses Top, Center or Bottom, with centered lines. Choose another preset if the text covers the subject. Precise coordinates, rotation and left-aligned paragraphs need a different layout editor.

Why does changing the color affect the box or glow?

The meaning depends on the style: ordinary lettering uses it as the fill, the boxed look uses it behind contrasting letters, and the glowing look uses it for the glow. Check the rendered result after changing Color.

How can I make a caption readable on a busy background?

Try an outlined or boxed style and move the caption away from detailed areas. Keep the message brief and inspect the image at the size people will see it. An effect helps contrast but cannot make crowded wording easy to read.

Can I put two separate text boxes on one photo?

Only one caption block is available per run. You can save the first result, open that image and add another caption, but the earlier words are then fixed pixels. Keep the original if either caption may need revision.

Can I edit the lettering after reopening the exported image?

The exported image has no separate text layer to select. Reopen the uncaptioned original and enter the revised wording to make a new version. Saving a captioned file does not preserve an editable design project.

Which picture formats work, and what type is saved?

For captions, start with a JPG, PNG, WebP or HEIC picture. JPEG and WebP inputs retain their respective output types; other accepted inputs are saved as PNG. An iPhone HEIC source is converted locally for processing rather than exported as HEIC.

Can I put lettering on a transparent PNG?

Yes. Drawing text does not fill the whole canvas with a solid background. Empty areas outside the caption remain transparent in the PNG output; a boxed style makes the area directly behind its lines solid.

Does adding a caption reduce the picture resolution or quality?

The working canvas retains the decoded dimensions when they fit the device. Larger sources can be scaled down, and saving with lossy compression can change pixel detail. Check the reported resolution and inspect small letters in the saved file.

Can I add a caption on iPhone or Android?

Use a current browser on your phone and select the photo from your device. The same style controls draw the caption locally. If the phone runs out of memory drawing the caption, use a lower-resolution photo or finish the lettering on a computer.

Is my picture sent to a server when I add words?

No photo upload is used for this edit. The browser combines the image and caption locally. Loading the website and fonts, or reporting a processing error, can still require network requests.

Can I add a description underneath the image on a new strip?

This tool places the caption inside the existing photo boundaries. It does not add a blank strip below the picture or enlarge the canvas for a description. Use a layout editor when the words must sit outside the photograph.

Can the text sit behind a person or building?

No. The caption is drawn over the image without separating its subjects into layers. Placing words behind a subject requires a mask or a layered composition elsewhere.

Can this replace a misspelled word already on a sign?

It only adds your caption; the old word stays in the photo. Use Photo Text Changer for existing lettering, then check the replacement before adding any separate caption here.

Do I need to sign up or sign in to use the add text to an image, free?

Your first 2 downloads are free with no account. Sign in free for 8 more. Any paid Imagera plan makes downloads unlimited, and adds AI credits for the paid tools. Processing and the preview are always free.

Will the download have a watermark?

Your first 2 downloads and every download on a paid plan have none. Free downloads 3 to 10, after sign-in, carry a small “Made with imagera.ai” badge in the corner. The result on screen is always clean.

Can I add the same caption to several photos in a batch?

Batch processing needs any paid Imagera plan; one file at a time is free.
