Supported variants

Static images only. PNG: non-interlaced 8-bit RGB/RGBA; no EXIF/ICC or compressed text. JPG: 8-bit RGB/grayscale; no EXIF/ICC or CMYK. WebP: no animation, ICC, EXIF or XMP. Renaming an extension does not change its format.

TIFF: one uncompressed classic page, 8-bit grayscale/RGB/unassociated RGBA, top-left chunky pixels. Compressed, tiled, multipage, profiles, EXIF and unknown tags are rejected.

BMP: standard 40-byte DIB header, uncompressed 24-bit RGB, no palettes or profiles. Top-down and bottom-up row order supported.

    A clear view of every change

    Add an image to inspect your original, adjust settings and create a real download.

    Output settings image output

    Change format or lossy quality and compare the actual byte sizes. Re-encoding can increase file size. PNG uses the browser encoder; this is not a specialized lossless optimizer.

    About this tool

    Choose JPG, WebP or PNG and compare the real exported file size, with lossy quality controls where supported.

    Supported input
    PNG, JPG, WebP, TIFF, BMP
    Output format
    JPG, WebP, PNG
    Batch size
    Up to 5 files; format and combined limits below still apply.

    How it works

    1. Add Supported PNG / JPG / WebP / TIFF / BMP files in Input. Review each thumbnail and its validation status.
    2. Choose an output format. Adjust JPG/WebP quality or JPG transparency background, then create and inspect the export.
    3. Create the selected files. Compare original and result, then download an individual file or ZIP. Changing settings marks older results out of date.

    Supported files and limits

    Up to 5 files, 10 MiB each and 25 MiB combined. Each image must fit within 8192 pixels per side and 20 million pixels; a batch is limited to 40 million input pixels. Output is limited to 20 MiB per file and 50 MiB combined. One isolated image job runs at a time, with a 30-second timeout and cancellation.

    A practical example

    Compare JPG, WebP and PNG exports of a supported image using the actual reported sizes. Select JPG background colour if the source has transparent pixels.

    Troubleshooting this tool

    Changing format can remove alpha or introduce lossy artifacts. There is no guaranteed saving and PNG has no quality slider; evaluate the downloaded file for its intended use.

    PNG input must be non-interlaced, 8-bit RGB or RGBA. Animated PNG, EXIF, ICC profiles and compressed/international text metadata are rejected before decoding.

    JPG input supports 8-bit baseline/progressive RGB or grayscale. EXIF/ICC/multi-picture metadata and CMYK are currently rejected, so orientation and colour profiles are not silently discarded. Export an unprofiled copy from your image editor if needed.

    WebP input must contain one static image. Animation, ICC profiles, EXIF, XMP and unsupported container chunks are rejected. Both lossy and lossless input bitstreams are decoded by the browser; this tool does not promise lossless WebP output.

    TIFF input supports one uncompressed classic TIFF page, top-left orientation, chunky unsigned 8-bit grayscale, RGB or RGB with unassociated alpha. BigTIFF, compressed/tiled/multipage files, palettes, CMYK, profiles, EXIF and unknown tags are rejected. Resolution metadata is not retained.

    BMP input requires uncompressed 24-bit RGB with a standard 40-byte DIB header, no palette/profile and exact padded row bytes. Both top-down and bottom-up rows are supported. Other BMP variants are rejected.

    Check the actual export

    PNG uses the browser encoder without a quality control. Re-encoding can increase size; savings are measured from actual bytes and never guaranteed. JPG flattens alpha, while PNG/WebP retain supported transparency. Inspect downloaded dimensions, transparency and fine edges before replacing an original. Browser encoders differ; a quality setting is not a universal fidelity score, and file size may increase.

    Files stay in your browser

    No file bytes are uploaded. Ordinary work stays in memory. Choosing a “Continue” action saves that result in this browser for up to 30 minutes, so another compatible working tool can use the actual output. Saved workflows are limited to 50 MiB and 20 files; clear them in Output. Expired entries are removed on later tool visits. Clearing references is not a secure-erasure promise.

    If a file fails

    Check its actual format and the restrictions above. Renaming a file does not convert it. A failed file does not erase successful batch results. If processing times out, cancel and try fewer or smaller files. A current browser with worker canvas support is required.

    Before you use the download

    • Compare the actual output byte size with the source; a new encoding can be larger.
    • Inspect fine edges, gradients and any transparency background in the downloaded image file.

    Tools that accept this output

    These links use this tool's default output format, subject to each next tool's supported variants and limits. If you change the export format, use Continue in Output to see compatible actions for the actual result. Opening a link below starts another tool without transferring a file.

    • Convert JPG to PNG — Decode a supported JPG into a PNG without adding further lossy JPG encoding.
    • Convert JPG to WebP — Create a static WebP from a supported JPG and compare the actual size and quality.
    • Resize JPG images — Resize supported JPG files with independent dimensions or locked proportions.
