What is Add Timestamp to Image?
A visible date-and-time stamp turns any photo into a verifiable record. Construction managers use them to prove progress milestones, insurance adjusters attach them to claims, and real-estate inspectors include them in every report. Unlike EXIF metadata. Which platforms like WhatsApp and Facebook strip on upload. A burned-in timestamp survives re-compression, screenshotting, and format conversion because it is part of the image pixels.
Why use this tool?
Drag the stamp anywhere on the image. Bottom-right for unobtrusive documentation, center for prominent proof. Choose from full ISO timestamps (2026-04-14 09:32:15), date-only, time-only, or build a custom pattern with strftime tokens. Adjust font size (20–72 px), text color, background tint, and opacity so the stamp is readable against any scene without overpowering it. Everything runs in-browser via the Canvas API. Your photos never leave your device.
Common use cases
Stamp photos when you need at-a-glance proof of timing: daily site documentation, move-in and move-out inspections, food-safety compliance photos, veterinary checkup images, or volunteer event logs. It is also handy for personal projects. Timestamped renovation photos, baby milestones, and garden progress shots are far easier to organize than relying on file-modified dates.
How to use Add Timestamp to Image
- 1Drop a JPG, PNG, WebP, or BMP onto the upload area (or tap Browse on mobile)
- 2Pick a date/time format: Full, Date Only, Time Only, or Custom
- 3Drag the overlay to the desired spot on the image
- 4Tweak font size, colors, and opacity until the stamp is clearly readable
- 5Click Download. The stamped image saves at original resolution with no watermark
Frequently asked questions
- Can I set a custom date instead of today?
- Yes. Switch to Custom format and type any date and time you need. The tool does not restrict you to the current timestamp. Handy for retro-stamping older photos.
- Will the timestamp survive if I share the image on social media?
- Yes. The stamp is baked into the pixel data. Platforms may re-compress the JPEG and strip EXIF, but the visible text remains intact.
- Does stamping reduce image quality?
- The image is decoded once into a full-resolution Canvas bitmap. The timestamp is rendered as vector text. On export, you get the same pixel dimensions as the original. Only the area under the stamp text is changed.
- Does my photo get uploaded to a server?
- No. The entire process runs inside your browser using the Canvas API. Your photo never leaves your device, making this the most private timestamp tool available.
- What image formats are supported?
- JPG, PNG, WebP, and BMP are all supported. The download is always a high-quality PNG at the original resolution, preserving every pixel of the original photo.
- Can I add a date stamp to a photo taken years ago?
- Yes. You can set any custom date. Past or future. This is useful for organizing old photo archives or retro-stamping scanned prints.

JPEG and Timestamps: What You Need to Know
JPEG is a lossy format. Every time you open a JPEG, edit it, and re-save, the file goes through another round of compression. Theoretically, that means quality could degrade each time you add a stamp and export.
In practice, with our tool, quality loss is negligible because:
- The image is decoded once into a pixel-perfect Canvas bitmap.
- The timestamp is rendered as vector text directly on the Canvas.
- On export, you can choose maximum JPEG quality (100 %) or download as PNG to avoid any re-compression at all.
If your original JPEG is 4000 × 3000 px, the stamped output will be exactly 4000 × 3000 px. No resizing, no cropping unless you choose to.
Step-by-Step: Stamping a JPEG
- Upload the JPEG. Drag it onto the tool above or click "Browse." The tool detects the format automatically.
- Select a date format. "Full" gives you
2026-04-14 09:32:15. "Date only" drops the time. "Custom" lets you type anything (e.g.,%d/%m/%Yfor European-style dates). - Position the stamp. Drag it to the desired corner or center. For JPEG documentation photos, bottom-right is conventional.
- Adjust style. Bump the font size up for high-res JPEGs (48–60 px for 12+ MP images). Use a semi-transparent black background for readability against any scene.
- Download. Choose JPEG for the smallest file or PNG for lossless output. Either way, the timestamp is permanently baked in.
Where JPEG Timestamps Are Used
Construction & Engineering
Site engineers shoot hundreds of JPEGs per week on standard-issue smartphones. Stamped photos go straight into the daily progress report. No one has to right-click → Properties → Details to check the date.
Insurance Claims
After property damage, stamped JPEG photos are attached to claims as evidence. Adjusters prefer visible timestamps because they're faster to verify than EXIF data and cannot be silently edited.
Medical & Veterinary Records
Wound-care documentation, post-operative photos, and veterinary checkup images all benefit from a visible date stamp. The timestamp becomes part of the patient record without any special medical-imaging software.
Food Safety & Compliance
Restaurant managers photograph refrigerator thermometer readings, cleaning checklists, and delivery receipts. Stamped JPEGs prove compliance during health inspections.
JPEG EXIF vs. Visible Timestamp
Every JPEG carries an EXIF header with the camera date embedded. So why add a visible stamp?
- EXIF is fragile. Many platforms strip it: WhatsApp, Facebook Messenger, Instagram, Imgur, and most webmail clients. A visible stamp survives all of these.
- EXIF is invisible. You need a tool or right-click → Properties to see it. A visible stamp is readable at a glance.
- EXIF is editable. Free tools like ExifTool let anyone change the date. Pixel-embedded text is much harder to tamper with undetectably.
Quality Tips for JPEG Timestamps
- Use PNG export if quality is paramount. PNG is lossless, so there is zero re-compression. The file will be larger, but the pixels will be perfect.
- If you must stay in JPEG, export at quality 95–100 %. The visible difference between 95 % and 100 % is virtually zero, but the file-size savings at 95 % are significant.
- Avoid repeated saves. Stamp the JPEG once and treat the output as the final version. Don't re-open and re-save repeatedly.
- Keep the original. Always retain an un-stamped copy as your master file and apply the stamp to a copy.
After Stamping Your JPEG
Depending on your workflow, you may want to:
- Compress the JPEG to hit an email-attachment limit (many organizations cap attachments at 10 MB).
- Resize the image for a web gallery or social-media post.
- Crop the image to highlight the relevant area of the scene.
- Add extra text such as a project code, property address, or patient ID alongside the timestamp.
FAQ
Will the timestamp survive if I upload the JPEG to social media?
Yes. The stamp is part of the image pixels. Social-media platforms may re-compress the JPEG and strip EXIF, but the visible text remains intact.
Can I stamp a JPEG photo taken years ago?
Absolutely. Use the "Custom" format option to type the original date. The tool does not restrict you to the current date.
What about HEIC / HEIF images from an iPhone?
iPhones shoot in HEIC by default. If your device converts to JPEG when sharing, that JPEG works perfectly. You can also change your iPhone camera settings to shoot in JPEG directly (Settings → Camera → Formats → Most Compatible).
