Batch Convert Images — Multiple Files, One ZIP Download
Drop a whole folder, pick a format, and walk away with a single ZIP. No queue, no uploads, no repetitive clicking.
Drop your image to convert

How Our Privacy Engine Works
When you drop an image onto VisualConvert, our code runs entirely inside your device's web browser using modern web standards (Canvas API & WebAssembly). Unlike traditional converters that upload your photos to remote servers, process them there, and send them back, VisualConvert processes everything locally in your computer's memory. You can verify this anytime: open your browser's Developer Tools (F12), switch to the Network tab, and drop a file — you will see zero upload requests!
Whole folders in, one tidy ZIP out
Converting a single image is a five-second job. Converting three hundred of them, one at a time, is how a Tuesday afternoon quietly evaporates. Batch mode collapses that repetition into a single action: point it at everything, choose the format you want, and let it churn through the pile while you do something more interesting.
Everything is packed into one ZIP at the end, so you are not fishing hundreds of separate downloads out of your browser’s bin. And because the conversion happens on your own machine, the size of the pile does not summon an upload progress bar.
Who really needs bulk mode
A photographer emptying an SD card ends up with hundreds of identically-named RAW exports that all need to become web-ready JPGs. An online seller with a fresh product line has a gallery of PNGs that each need the same treatment before they hit the store. A developer inheriting an assets folder wants every stray image nudged into one modern format. Bulk mode is built for exactly these piles.
The time math is not subtle
Say each manual conversion — open, pick format, save, repeat — costs you roughly eighteen seconds of clicking. Across a hundred files that is half an hour of pure tedium. Drop the same hundred into batch mode and they finish in well under a minute. The bigger the pile, the more lopsided that trade becomes.
Drag a folder, not a hundred files
You do not have to shift-select every thumbnail. Drag the folder itself onto the drop zone and every image inside is queued at once. Mixed contents are fine — the converter picks out the images and ignores the stray text file or spreadsheet that wandered in.
Big piles, still nothing uploaded
Scale does not change the privacy story here. Whether it is five files or five hundred, each one is decoded, converted and re-encoded in your browser’s memory and never touches a server. The ZIP is assembled locally too, so the entire job — start to finish — stays on your device.

Frequently Asked Questions
How many files can go into one batch?
The free tier handles up to 5 files per run, which covers most everyday jobs. Paid plans lift the ceiling — 20 files on Weekly, 40 on Monthly and up to 50 on Yearly — with larger per-file limits, aimed at photographers and sellers moving whole galleries at once.
Can I drop an entire folder instead of picking files?
Yes. Drag the folder straight onto the upload area and every image inside is added to the queue automatically — no need to open it and select each picture by hand.
Do I get one ZIP or a flood of separate downloads?
One ZIP. Every converted image is bundled into a single archive that downloads in one go, so your Downloads folder stays tidy no matter how large the batch was.
Do all the images have to start in the same format?
No. You can mix HEIC, PNG, WebP and JPG in the same batch and send them all to one chosen output format. The converter reads each file’s type on its own.
Is there a cap on total batch size?
Limits apply per file rather than to the whole pile. Free allows 25 MB per file, and paid plans raise that ceiling by tier — up to 120 MB per file on Yearly. Since processing is local, the practical limit is really your device’s available memory, not a server quota.
About Batch Convert Images
Converting one image at a time is fine until you have a folder of them. A batch convert lets you drop in the whole set, choose one output format, and get every file back at once. It saves the repetitive work of opening, converting and saving each photo by hand, which is the slow part of any bulk job.
VisualConvert runs the whole batch in your browser, so none of the files are uploaded. You can even mix formats in one go — HEIC, PNG and WebP together — and send them all to a single output format, then download the results as one ZIP. The free tier handles 5 files per batch; paid plans raise that to as many as 50.
Why use VisualConvert
- Convert a whole folder to one format in a single pass
- Mix input formats — HEIC, PNG, WebP — in the same batch
- Download every converted file together as a ZIP
- Runs in your browser; nothing is uploaded
Frequently Asked Questions
How many images can I convert at once?
The free tier converts up to 5 images per batch, with no limit on how many batches you run. Paid plans raise the batch size by tier, up to 50 files at a time on the top plan.
Can I mix different input formats in one batch?
Yes. You can drop HEIC, PNG, JPG and WebP files into the same batch and convert them all to one chosen output format — the tool reads each file’s type on its own.
How do I download all the converted files?
After the batch finishes, download everything together as a single ZIP rather than saving each file one by one.
Are the files uploaded to convert them in bulk?
No. The whole batch is processed on your own device in the browser, so even a large folder of images never leaves your computer.
Can I also resize or compress the whole batch?
Yes. Alongside the format, you can apply one quality setting, a target file size, or new dimensions across the entire batch at once.
