Resize Image to 3000x3000
Make a batch of images exactly 3000 x 3000 px, padded or cropped, without uploading them.
To resize image to 3000x3000, use this free tool to set each photo on a square canvas of 3000 × 3000 px. It runs in your browser, so photos are read and processed inside the page and are never uploaded. No sign-up is needed. You can add up to 100 photos per batch with “Choose photos” or by dropping files on the box, then download each result.
3000 × 3000 px is the only size in this tool’s menu, and it is 9 megapixels. It is not an Amazon rule. Amazon’s help page publishes a range of 500 to 10,000 px on the longest side, and 3000 px falls inside that range. Check the help page for its current wording before you list.
How to use the 3000 × 3000 resizer
- Open the “Output size” menu and confirm that “Square, 3000 × 3000 px” is selected.
- Click “Choose photos” or drop your files onto the box. To try the tool first, click “Try a sample photo.”
- Under “How the photo fits the frame,” choose “Keep the whole photo (add background around it)” to pad the photo, or “Fill the frame (cut off the overflow)” to crop it.
- If you chose the fill option, pick a “Crop focus”: Centre, Top, Bottom, Left or Right.
- Set “Background colour” for the bars around a padded photo. The default is #ffffff.
- Tick “Never enlarge small photos” if you want small photos kept at their own size. Leave it off to scale them up to fit.
- Choose a file type. JPEG is the default, and PNG and WebP are also offered.
- Optional: enter a limit under “Keep each file under,” in KB or MB.
- Check each card. It shows the “Original” size, “Output size,” “File” size, and any notes or checks.
- Click “Download” on a single card, or click “Download ZIP (first 10)” when two or more photos are ready.
The tool recalculates every photo when you change an option, so you can adjust settings and check the cards again before you download. Use “Clear all” to empty the list and start over. For file names, the pattern tokens are {name}, {n}, {lot}, {w} and {h}, which stand for the original name, position, lot number and output size.
How does a photo fit inside a 3000 × 3000 px square?
The tool scales each photo so it fits inside a 3000 × 3000 px square. Then it either adds bars to fill the spare space or cuts off the overflow, depending on the fit option you choose.
For a 4,000 × 3,000 photo with “Keep the whole photo” selected, the photo is drawn at 3,000 × 2,250 px, with 375 px bars above and below. A 1,500 × 1,500 photo is drawn at 3,000 × 3,000 px with no bars.
What does “Keep the whole photo” do to a wide or tall image?
It keeps every part of the photo visible and adds background around the shorter sides. The bars use the colour set in “Background colour.” Transparent areas are filled with that same colour, so the output never has transparency.
When does “Fill the frame” cut off part of a photo?
It scales the photo until the square is covered, then removes the overflow. “Crop focus” decides which part stays. For a 4,000 × 3,000 photo with “Crop focus” set to Centre, the tool keeps a 3,000 × 3,000 px area starting at x 500 and y 0, then scales it to 3,000 × 3,000 px.
What happens to a photo smaller than 3000 px?
“Never enlarge small photos” is off by default, so a small photo is scaled up to fill the square. When a photo is enlarged, its card says by how many percent. An enlarged photo has no extra detail, so check that percentage. Ticking the box keeps the photo at its own size inside the 3000 px canvas.
Does the tool remove or whiten a background?
Not in general. The “Whiten a greyish background (white point)” slider runs from 200 to 255, where 255 is Off. Every colour value at or above the chosen number becomes 255, so a light grey backdrop turns white. It brightens the whole photo slightly. It does not remove or replace a coloured background, shadows or clutter.
“Trim white margins and fit the product to [85] %” works only on a white or nearly white backdrop. It treats any pixel that is not transparent and has red, green or blue below 245 as product, crops the empty margin, and centres the product within the chosen percentage of the frame. If the photo has no white margin, it finds nothing to trim and says so.
Why does the file size limit skip PNG files?
“Keep each file under” lowers the JPEG or WebP quality until the file fits. If quality alone is not enough, it shrinks the pixels in steps. PNG files cannot be reduced this way, so the tool does not apply the limit to PNG and says so.

Frequently asked questions
Can I resize image to 1000x1000 or 1600x1600 on this page?
This page’s “Output size” menu lists only “Square, 3000 × 3000 px.” The “Custom size…” option lets you enter Width (px) and Height (px), so you can set other square sizes there.
Is 3000 × 3000 px a requirement for Amazon?
No. Amazon’s help page publishes a range of 500 to 10,000 px on the longest side, and 3000 px is inside that range. The range is not a rule for any particular size, so check the help page before you list.
Are my photos uploaded when I resize them?
No. Photos are read and processed inside the browser and are never uploaded. The tool is free and needs no sign-up.
Does saving a photo remove its location data?
Yes. A file saved through the tool is written without the original’s camera, date and location (EXIF) data. HEIC photos from an iPhone may not open outside Safari; if yours does not, export it as JPEG first.
Can I download every photo in a batch as one ZIP?
The free “Download ZIP (first 10)” button holds the first 10 results. Whole-batch ZIPs are a planned Pro feature, and nothing paid exists yet.
Does resizing make a marketplace accept my photo?
No. The tool sets the size, file type and layout of each photo. It does not check a marketplace’s acceptance rules, so read each marketplace’s own help page for its current numbers.
