Bulk Image Resizer & Converter

Q: Does this upload my photos to a server?

No—everything runs locally in your browser. Your images are not uploaded.

Q: What’s the difference between Fit, Fill, and Crop?

Fit keeps aspect within a bounding box (no padding); Fill pads to exact size with your background color; Crop covers the box and trims overflow for consistent thumbnails.

Q: How do I compress images in bulk?

Choose WebP or lower the quality slider, process your selection, and download the ZIP. That’s the quickest bulk compression workflow.

Q: Is there a limit on image size or count?

Limits depend on your device and browser memory. Very large images or huge batches can hit canvas limits—process in smaller groups if needed.

TL;DR — bulk resize, convert, watermark, and zip in your browser

Drop your images, pick a preset or size, choose WebP/JPEG/PNG, add an optional text or logo watermark, then download individually or as a ZIP. No uploads, no tracking—everything runs locally.

Bulk Image Resizer & Converter — built for real‑world workflows

When you’re prepping a batch of visuals, you don’t want a heavyweight app or another upload gate. You want a quick, predictable tool that respects your time and your files. This bulk image resizer runs entirely in your browser, so you can resize multiple photos, convert formats, add a watermark, and export a clean ZIP without sending anything over the network. It’s ideal for creators, social teams, product marketers, and engineers tidying assets before they ship.

Start with the size you need: keep aspect with Fit, pad to exact dimensions with Fill, or enforce consistent thumbnails with Crop (cover). Prefer simple scaling? Use Percent for quick downsizing or Long edge for mixed orientations. Export as WebP, JPEG, or PNG (or choose Auto — PNG if alpha, otherwise JPEG). Fine‑tune output with a quality slider, background color for padding, and optional rotate/flip transforms.

Watermarks are built in. Add a lightweight text mark or drop in a logo image; choose position (corners or center), adjust margin, opacity, and relative size, and you’re done. To keep filenames consistent across a campaign, use the template tokens ({name} {w} {h} {ext} {i}) and download everything as a single ZIP.

How to use the Bulk Image Resizer & Converter

Upload your images
Drag & drop or click to add multiple files. Use Select all/none, or pick items one by one.
Choose a preset or mode
Pick Square/Social presets or select Fit, Fill (pad), Crop (cover), Scale by %, Long edge, or Original (no resize). Lock proportion and prevent upscaling if you want to avoid soft results.
Set format, quality, and options
Export as WebP/JPEG/PNG (Auto uses PNG when alpha is present). Adjust quality, background color for Fill, rotate/flip, and add either a text or logo watermark.
Process and download
Process selected/all, then download individual files or a ZIP. Filenames follow your template tokens: {name} {w} {h} {ext} {i}.

Guide

When to use which mode: choose Crop when every image must be exactly the same visible size (e.g., product grids). Use Fit to preserve composition without padding. Pick Fill for hero areas that require precise dimensions and a background color. For mixed orientations, Long edge normalizes the longest side, while Percent gives you quick, proportional scaling across a set.

Quality & formats: WebP usually delivers the best size/quality ratio; JPEG is a good choice for photographic content when WebP isn’t required; PNG is ideal when you need lossless or transparency. If you’re unsure, start with WebP ~80% and adjust by eye.

Note: very large images or huge batches depend on your device’s memory (browser canvas limits). Exports focus on pixels and may not retain EXIF/metadata.

Tips

Use WebP + quality 70–85 for big size savings with good perceptual quality.
Pick Crop (cover) for consistent thumbnails; Fit to preserve original aspect without padding.

Frequently asked questions

Does this upload my photos to a server?

No. Everything runs locally in your browser.

What’s the difference between Fit, Fill, and Crop?

Fit keeps aspect within your box (no padding). Fill pads to exact size with a background color. Crop covers the box and trims overflow for pixel-perfect thumbnails.

How do I compress images in bulk?

Choose WebP or lower the Quality slider, process, and download the ZIP. That’s the quickest way to bulk compress images.

Will metadata (EXIF) be preserved?

Exports focus on pixels; EXIF/metadata may not be retained in the output.

Is there a limit on image size or count?

It depends on your device and browser memory. Extremely large images or huge batches may hit canvas limits; process in smaller groups if needed.
