Batch image resizer — resize 50 images to print-ready at once
Upload 1–50 images and get every one back at the correct print size — 2048px or 4096px — with 300 DPI metadata stamped automatically. No Photoshop, no scripts, no per-file clicking. Download everything as a single ZIP.
§Key Features
Up to 50 images per batch
Drop a full product set in one go — up to 50 images processed together. Each file gets the same size treatment so your whole catalogue stays consistent.
300 DPI stamped on every output
The DPI metadata is written into each file automatically. You won't get a customer complaint about blurry prints because you forgot to set resolution.
Single ZIP download
All resized files arrive in one ZIP. No waiting for individual downloads, no renaming, no reassembling from a downloads folder.
Choose 2048px or 4096px output
Pick the long edge before you run the batch — 2048px for standard POD listings, 4096px for large-format or high-end print products. One setting applies to the whole batch.
AI upscale for low-res inputs
If your source images are under resolution, the AI upscaler brings them up before resizing. Older artwork or scanned originals can reach 2048 or 4096px without obvious degradation.
§How it works
§01
Upload your images
Drag up to 50 PNG, JPG, WebP, TIFF, or HEIC files onto the batch resizer. Mixed formats are fine — they all process together.
§02
Choose your output size
Select 2048px or 4096px as the target long edge. This applies to every image in the batch, so pick whichever your POD platform or product requires.
§03
Run the batch
The resizer processes every image in the cloud — no software to install, no waiting for your laptop to chew through 50 files. Takes seconds for most batches.
§04
Download the ZIP
All resized files come back as a single ZIP. Every image has 300 DPI metadata baked in and is ready to upload directly to Etsy, Printify, Printful, or any POD platform.
§Specifications
When you’d use this tool
Four scenarios where this tool saves the most time:
- Setting up a new Etsy shop. You have 30–40 designs ready and need every one at print resolution before you start listing. Run them all through the batch resizer in one go instead of opening each file in Photoshop.
- Refreshing an existing catalogue. Older listings were uploaded before you knew about DPI requirements. Pull the originals, batch them through at 4096px, re-upload — your whole back-catalogue gets fixed in under an hour.
- Automating a production workflow. If you're producing new designs regularly, batch resizing keeps your file-prep step consistent: same size, same DPI, same output format every time, without making decisions on each image individually.
§Common mistakes
Things to watch for, in approximate order of how often I see them:
Skipping DPI metadata
Resizing to 2048px or 4096px gets the pixel count right, but if the DPI tag says 72 or 96, some print labs and POD platforms will flag the file as low-resolution. Always confirm 300 DPI is written into the file, not just assumed.
Using the wrong output size for the product
2048px is enough for most standard POD products, but large-format prints (24×36in and up) need 4096px to hold sharpness. Check your platform's spec sheet before running the batch — re-running 50 files because you picked the wrong size costs time.
Resizing without checking aspect ratio first
Batch resizers preserve aspect ratio by default, but if your source images are different shapes and your product needs a specific ratio, you'll get outputs that don't fit without cropping. Review your source dimensions before batching, or run the wall art converter first to standardise ratios.
