Convert TIFF to JPG

Choose the TIFF page before making a JPG

JPEG stores one rectangular image. TIFF can hold a sequence of pages. Those facts make page choice part of the conversion rather than an advanced option: when the source has more than one top-level image directory, this tool requires you to select the exact page. It does not export page one by habit and leave the remaining pages unmentioned.

The inventory arrives first. Each row identifies its one-based page number, stored and upright dimensions, orientation, compression, color interpretation, sample depth, alpha, and resolution. Selecting another row updates the preview and planned receipt without rereading the file. The download name always includes the decision — scan-page-3.jpg, for example — even when the TIFF contains only one page.

TIFF to JPG is deliberately a lossy conversion

TIFF is a container and can store pixels without loss, with simple run-length compression, or with another codec. JPEG always introduces a new lossy generation. Its strength is a compact, widely accepted photographic file; its cost is discarded detail around edges and texture. The quality setting controls that trade, and the receipt describes the output as a new JPEG encode rather than “preserved quality.” No setting can restore information already absent from a compressed TIFF page.

For diagrams, text scans, palette artwork, sharp screenshots, or anything that must retain the decoded 8-bit pixels exactly, TIFF to PNG is the safer sibling. If the source is a multi-page document rather than one picture, use TIFF to PDF to keep the selected pages together instead of converting them one at a time.

Transparency has to become a visible color

JPEG has no alpha channel. When a decoded page contains declared, genuinely transparent pixels, a solid background choice appears before conversion with white as its default. Associated TIFF alpha is unpremultiplied before compositing; unassociated alpha is used directly. Extra samples that are not declared as either alpha form are rejected, because treating an unknown channel as opacity can erase color data while producing a file that still looks valid.

The receipt says Alpha: Removed and records the chosen color separately as Background: #rrggbb; JPEG quality remains visible too. When the page is fully opaque, the background control is absent because it could not change a pixel. Controls without an effect make a converter look flexible while concealing which decisions actually matter.

Upright pixels replace an orientation note

A TIFF can say that its stored rows should be mirrored, rotated, or both. The page preview and output use all eight orientation values. Pixels are normalized and dimensions are swapped where necessary; the JPG does not need a new EXIF orientation tag to look correct. Reopening checks asymmetric corners, not just dimensions, so a mirrored result cannot pass because it happens to have the expected width.

Supported unsigned sixteen-bit grayscale samples must also cross a visible boundary. JPEG's browser encoding path is eight-bit, so values are deterministically scaled and the receipt says 16-bit source to 8-bit output. Signed and floating-point TIFF samples are outside this route and receive a typed unsupported message.

Color and metadata are not silently carried

The supported grayscale, RGB, and palette pages are decoded to an sRGB-like eight-bit working image. Embedded ICC bytes are neither applied nor copied. GeoTIFF positioning, camera metadata, scanner-private tags, thumbnails, and other directories are not written into the JPG. This makes the file suitable as a general viewing or delivery copy, not as a color-managed master, georeferenced dataset, or archival substitute.

Decoder support is explicit as well. Verified classic TIFF combinations use strips, contiguous samples, and the named raw, PackBits, LZW, Deflate, and bilevel fax paths. BigTIFF, tiled pages, JPEG-compressed TIFF, planar color, Predictor 3, signed or float samples, CMYK, YCbCr, Lab, and unknown combinations stop with the reason. Renaming one of those files cannot force it through because the first bytes and page tags, not the suffix, decide the format.

A receipt that exposes every irreversible step

The finished panel identifies source page count, chosen page number, source and oriented dimensions, compression and bit depth, orientation action, alpha/background action, profile and metadata handling, JPEG quality, and output bytes. The download appears only after an independent reopen confirms JPEG magic, measured dimensions, and asymmetric pixel samples. If another page or quality is needed, change the controls and run again from the retained TIFF.

Large files are not refused by a hard size limit. The page gives memory advice before work, then lets you continue locally and cancel an honest worker task. Nothing is uploaded or written into URL or storage state. You can verify that boundary with the network-checking guide.
