Convert multiple JPG, PNG, WEBP, AVIF, GIF, BMP, HEIC, or SVG files at once and download all converted images in a single ZIP archive.
Converting images one at a time is impractical for batches of 20, 50, or 100 files. This tool converts JPG, PNG, WebP, AVIF, GIF, BMP, HEIC, or SVG files - all files in a batch must share the same source format, converted to one target format of your choice (GIF, BMP, and HEIC can be used as a source but not as an output target).
Everything runs in your browser and packages the results into a downloadable ZIP; each output filename keeps its original name with a short suffix added. No server upload, no login.
Bulk image conversion handles the repetitive task of format-changing dozens of images at once - what would take an hour of one-by-one conversions becomes a single upload-and-download workflow. Pick one source format and one target format, select your files, and download every converted image in one ZIP.
Select the source format and target format from the two dropdown menus.
Upload multiple images in one go using multi-select file upload.
Each image is converted in your browser and added to a ZIP archive.
Download one ZIP file containing every converted image, each keeping its original filename plus a short suffix.
Convert an entire product photo library from one format to another, such as PNG to WebP.
Convert a batch of HEIC photos from an iPhone to JPG for universal compatibility.
Convert a folder of SVG icons to PNG for use in an app or design tool.
Run the ZIP's contents through the Bulk Image Compressor afterward for smaller files.
For behavior details like transparency fill color, use the matching single-file converter, such as PNG to JPG.
Best For
Source Files
50 PNG product photos, selected via multi-select from one folderResult
One ZIP containing 50 WebP files, each named like photo-01_codittools.webpEvery file in the batch must share the same source format - one 'Convert From' and one 'Convert To' setting apply to the whole batch, not a per-file choice. Each output filename keeps the original name with a short suffix added before the extension.
Convert an entire batch of product images from PNG to WebP (or another supported pair) in one pass instead of one file at a time.
Convert a batch of iPhone photos exported as HEIC into universally compatible JPG files.
Convert a folder of SVG icons to PNG for a mobile app or platform that needs raster assets.
Problem
Solution
Selecting files that don't match the chosen 'Convert From' format gets them filtered out automatically, with a warning that only some files were added. Run a separate batch for each source format, or use the Bulk Image Compressor instead, which does accept mixed formats.
Problem
Solution
If any single file fails to convert - a corrupted image, for example - the entire batch stops and no ZIP is produced, even for the files that converted successfully. Remove the problem file and re-run the batch.
Problem
Solution
Converting a raster image (JPG, PNG, etc.) to SVG here wraps the original image inside an SVG container rather than tracing it into vector paths. For an actual vector trace, use PNG to SVG or JPG to SVG instead.
Problem
Solution
These three formats can be used as a source format but are not available as conversion targets - the target format dropdown only offers JPG, PNG, WEBP, AVIF, and SVG.
Since a batch requires every file to share the same source format, sort files by format first if your folder has a mix.
Behavior like transparency fill color can differ between tools - check the matching single-file converter (for example, PNG to JPG) if that level of detail matters for your files.
This tool focuses on format conversion, not file size. Run the ZIP's contents through the Bulk Image Compressor if you also need smaller files.
There's no partial-success handling - if any file in the batch fails to convert, the tool stops and no ZIP is downloaded, even for files that already converted successfully.
These formats are supported as a source format only. The output target is limited to JPG, PNG, WEBP, AVIF, and SVG.
Converting a raster image to SVG embeds it as a raster image inside an SVG wrapper - it does not generate vector paths. Use PNG to SVG or JPG to SVG for actual vectorization.
There's no hard cap on how many files you can select. Very large batches are limited by your device's available memory and browser performance, since everything processes in your browser.
Both convert formats client-side, but they trade off batch size against per-format detail and control.
| Bulk Image Converter | Single-pair converter (e.g. PNG to JPG) | |
|---|---|---|
| Files per run | Multiple files, one shared source and target format | One file at a time |
| SVG output | Embeds the source image in an SVG wrapper, not a true trace | PNG to SVG and JPG to SVG perform real vector tracing |
| Best for | Converting many files in the same format pair at once | A single file, or when format-specific behavior matters |
Which should you use?
Use the bulk tool for batches that share one source and target format. Use a single-pair tool when you need format-specific behavior or are only converting one file.
The most common question is whether files of different formats can go in the same batch - they can't, since the tool converts from one selected source format to one selected target format at a time. The FAQ below covers that limit along with filenames, failures, and format support.
No. You pick one source format and one target format for the whole batch - any selected file that doesn't match the chosen source format is filtered out automatically, with a warning that only some files were added. Run a separate batch for each source format, or use the Bulk Image Compressor instead, which does accept mixed formats.
Each file keeps its original name with a short suffix added before the extension - for example, logo.png becomes logo_codittools.jpg. The ZIP archive itself gets the same treatment.
There's no hard file-count limit built into the tool. In practice, very large batches are limited by your device's available memory and browser performance, since every file is processed in your browser.
The entire batch stops and no ZIP is downloaded, even for files that already converted successfully. Remove the problematic file and run the batch again.
No. GIF, BMP, and HEIC can be used as a source format, but they aren't available as target formats - the output dropdown only offers JPG, PNG, WEBP, AVIF, and SVG.
No. Converting a raster image (JPG, PNG, etc.) to SVG here embeds the original image inside an SVG wrapper rather than tracing it into vector paths. For an actual vector trace, use PNG to SVG or JPG to SVG instead.
