Resize a whole image set without repetitive editing
A bulk image resizer applies the same size, format and quality rules to an entire folder. Instead of opening files one at a time, you can prepare product photos, blog images or social assets in a single browser workflow and download the completed set together.
Scenyra processes resizing locally on your device. The selected images are not uploaded to Scenyra or an external image service, so this tool is useful when you need a fast, private way to prepare routine image assets.
One rule for the full batch
Use a platform preset, maximum dimensions, an exact canvas or a percentage scale.
Consistent downloadable output
Keep the original format or export JPG, PNG or WebP, then download the batch as a ZIP.
Resize a folder in three steps
The tool keeps the setup short while still providing the controls needed for common publishing workflows.
Add your images
Choose or drag in up to 40 JPG, PNG or WebP files. The queue shows every selected file before processing begins.
Choose a resize rule
Pick a marketplace preset or set maximum dimensions, an exact output size or a percentage reduction.
Resize and download
Apply the rule to the full batch, review the output dimensions and download all completed images in one ZIP.
Built for the places you publish
Batch resizing is most valuable when many images must follow the same technical requirement.
E-commerce catalogues
Prepare consistent product images for Shopify, Amazon, Etsy and eBay without resizing every listing by hand.
Websites and blogs
Reduce oversized photos and convert them to a web-friendly format before adding them to a page or article.
Social media publishing
Create a consistent folder of assets for Instagram, Facebook, Pinterest or X using the included presets.
Design handoff
Normalize exported assets before sharing them with a developer, marketplace manager or content team.
Preset, maximum, exact or percentage?
Preset mode is the quickest option when a publishing destination already has a known image requirement. Maximum size keeps the original aspect ratio and limits the image within a width and height. You can leave one side empty when only one dimension matters.
Exact size creates a specific width and height. Crop fills the entire frame and trims overflow, Pad keeps the full image inside the frame, and Stretch forces the source into the requested dimensions. Percentage mode is designed for proportional reduction from 5% to 100%.
Choose an output format and quality
Keep original preserves each file type while resizing. JPG is usually the practical choice for photographs, PNG supports transparency and sharp graphic edges, and WebP is useful when smaller web assets are the priority.
The quality control affects compressed formats such as JPG and WebP. A lower setting can reduce file size, while a higher setting preserves more visual detail. PNG output is lossless, so the quality control is intentionally hidden for that format.
Popular marketplace and social image sizes
These common targets map to the presets in the tool. Always confirm current platform requirements for a specific placement or campaign.
| Platform | Common target |
|---|---|
| Shopify | 2048 × 2048 px |
| Amazon | 1600–2000 px |
| Etsy | 2000 px on the longest side |
| eBay | 1600 px on the longest side |
| 1080 × 1080 px | |
| 1200 px wide | |
| 1000 × 1500 px | |
| X / Twitter | 1600 px wide |
Tips for better resized images
- Start with the highest-quality source available, especially when you plan to crop or allow upscaling.
- Use maximum size when you need to preserve the complete composition and original aspect ratio.
- Use exact size only when the destination requires a fixed canvas or aspect ratio.
- Compare JPG and WebP output when page speed and download size matter.
- Keep an untouched copy of the source folder before running a large publishing batch.
Frequently asked questions
Is the bulk image resizer free?
Yes. The image resizer runs in your browser and does not use Scenyra credits. You can use it without creating an account.
Are my images uploaded anywhere?
No. Resizing, format conversion and compression happen locally in your browser, so the source images never leave your device.
Which image formats are supported?
You can add JPG, PNG and WebP images. Output can keep the original file type or convert the batch to JPG, PNG or WebP.
How many images can I resize at once?
Scenyra currently accepts up to 40 images in one resizing batch. The practical limit also depends on the memory available in your browser and device.
What is the difference between Max size and Exact size?
Max size keeps the original aspect ratio and fits an image within the dimensions you provide. Exact size creates a fixed width and height using Crop, Pad or Stretch.
Can the resizer make small images larger?
Preset and Max size modes include an Allow upscaling option. Conventional resizing can increase dimensions, but it does not rebuild missing detail like an AI upscaler.
What do Crop, Pad and Stretch do?
Crop fills the requested frame and removes overflow. Pad fits the whole source inside the frame. Stretch changes the image to the exact width and height without preserving its original proportions.
Will resizing reduce image quality?
Reducing dimensions removes pixels, and compressed formats can introduce some quality loss. Use the quality slider to balance visual detail and output size for JPG or WebP files.
Can I download the full batch together?
Yes. After processing finishes, Scenyra packages the resized images into one ZIP file for download.
